Belle II Membership

Tip
titleI am new to Belle II. What do I have to do?
Please refer to the page Belle II Newcomers. You need to register.
Tip
titleHow do I become a Belle II member and how do I get into the Belle II Membership Management System?
If you have DESY credentials to access the Belle II collaborative services such as confluence, you were automatically included in the Belle II Membership Management System (B2MMS). If not please refer to Belle II User Registration. With your registration you will be included in the Belle II Membership Management System (B2MMS).
Tip
titleWho is the representative of my institution (IR)?

Please ask your colleagues. We might also help you by email at b2-helpdesk_AT_belle2.org.

Tip
titleHow long does it take to get a Belle II membership?

Your membership request triggers an approval  workflow which involves the representative of your institution (IR), and the IB - if you are physicist / faculty/staff - followed by the creation of your DESY credentials (account name / password). The entire process is usually finished within one workday but obviously depends on the availability of people.

Tip
titleWhere is the Belle II members list?

Please refer to the official Belle II members list (protected).

Tip
titleMy membership 'Expired'.

If your affiliation with your current Belle II institution ends, e.g. after finishing a thesis, your current Belle II institution representative (IR) will set your Belle II membership to 'Expired'. Subsequently your DESY account for the Belle II collaborative services and tools will expired with a grace period of one month as well. See Belle II Membership Management System for information if you change to another Belle II institution. Do not register again, your record remains in the system.


Registration

Tip
titleAfter registration I received an email about the readiness of my account. How can I change the password?

Account and password are the ones you typed into the form at registration time.

Tip
titleThe certificate-based registration fails, because my name is not in the CN of my certificate.

The portal compares your name with the name in your certificate to avoid miss-use of stolen certificates. In this very rare case cancel the process and contact b2-helpdesk_AT_belle2.org.

Tip
titleMy initial password does not work. I am sure though that it is the right one.

The DESY registry needs some time (<=5h) to set up the credentials and notify the connected services. Please try again in a few hours. You will get an email if everything is set up.

Tip
titleWhy am I asked for my date and place of birth?

In order to uniquely identify you in our system, we have to know your date and place of birth. Be sure the information will not be used elsewhere according to the privacy rules.


Account and Password

Tip
titleWhat is an account?

Your DESY account is a 4-8 character string; case insensitive. The DESY account is not an email address! We recommend to use parts of your last name.

Tip
titleI have a already a DESY account?

Belle II collaborators who have already a DESY credentials should contact b2-helpdesk_AT_belle2.org . The credentials can be prepared for Belle II. A Grid user certificate and the membership in the VO 'belle' is strongly recommended though.

Tip
titleHow can I login to DESY?

Your credentials (account name / password) are good to login to DESY by ssh to bastion.desy.de. You will see your AFS home dir at DESY (DESY.DE).

Tip
titleWhen does my password expire?

Login by ssh to bastion.desy.de using your DESY credentials and type 'kinit'. Example:

bastion02: [~] kinit        
Password for xxx@DESY.DE:
Warning: Your password will expire in 33 days on Wed Mar 28 00:59:58 2018

In case you can't remember your password, please write to b2-helpdesk_AT_belle2.org.
An admin will set a temporary password and you will be asked to use this temporary password to log in to  https://password.desy.de/ and set a new one.

Tip
titleI forgot my password?

In case you can't remember your password, please write to b2-helpdesk_AT_belle2.org.
An admin will set a temporary password and you will be asked to use this temporary password to log in to  https://password.desy.de/ and set a new one.

Tip
titleWhat about capital letters in account names and email addresses?

In general account names and email addresses are case insensitive!

Tip
titleWhat are the DESY password requirements/rules?

Please refer to DESY Requirements for Account Names and Passwords .

Tip
titleWhat are the 'Conditions of Use for Information-Processing Systems at DESY' all about?

At the bottom of the request portal you are asked to agree to the 'Conditions of Use for Information-Processing Systems at DESY'. The underlying document contains links to pages which are not relevant for abroad users, such as the local work council 'http://www.desy.de/betriebsrat'.

Tip
titleHow long does it take to create my login credentials?

The creation of the login credentials is finished within one work day. Please note: DESY is in the Central European Time-zone (CET).

Tip
titleI want to change my password?

Use https://password.desy.de/ or (deprecated!) login to bastion.desy.de and use the command 'passwd'. It connects to the DESY registry which manages the access to afs, web pages, and Atlassian tools (confluence, stash, agira, bamboo). The Sympa ML server and Indico are not managed automatically. The account name / password is valid for all resources. Please denote DESY Requirements for Account Names and Passwords.

If the web service https://password.desy.de/ fails due to your network settings (we saw such cases), login via 'ssh password.desy.de'.

Tip
titleI changed my DESY password using 'passwd' on a DESY login host?

The command 'passwd' issued on a DESY login host, e.g. bastion.desy.de, connects to the DESY registry which manages the access to afs, web pages, and Atlassian tools (confluence, stash, agira, bamboo). The Sympa ML server and Indico are not managed automatically.

Tip
titleI lost my password?

If your password got lost we reset it for you, please contact b2-helpdesk_AT_belle2.org. Do not register again! Please denote DESY Requirements for Account Names and Passwords.

Tip
titleWhich resources can I use by default?

See Belle II Requesting Additional Resource Access.

Tip
titleWhat is my Belle II account at DESY good for?

The DESY Belle II credentials you got through the registration procedure can be used to access the new Belle II web pages and the new Confluence Wiki incl. JIRA and STASH.

Tip
titleDo I have to renew my Belle II account at DESY yearly as at KEK?

No, this is not necessary but you will be asked regularly to change your password. The account name / password is valid for all resources. Please denote DESY Requirements for Account Names and Passwords.

Tip
titleDo I have a DESY account?

 If you were able to or are still able to login to bastion.desy.de , you got DESY credentials earlier which can be used for Belle II. Contact b2-helpdesk_AT_belle2.org . A new registration attempt via the portal would fail.

Tip
titleRenewing / changing password?

The DESY credentials ( account name / password) are valid for all resources. Use https://password.desy.de/ . Please denote DESY Requirements for Account Names and Passwords.

Tip
titleEmail from the DESY registry that account expires?

DESY will take care! There is nothing you must do! According to the DESY (security) rules, accounts automatically expire but can be extended by an admin. As long as you are an active Belle II member according to your status in the B2MMS, your account will be extended.


Email Address


Tip
titleNames and email addresses.

The DESY registry will use the names you have given as 'given middle family' and create email addresses such as given.middle.family_AT_desy.de and given.middle.family_AT_belle2.org. Make up your mind if you really want the middle name. The spaces will be transformed to dots! Example: 'Nino de Angelo' will become 'nino.de.angelo_AT_desy.de' and 'nino.de.angelo_AT_belle2.org' whereas 'Nino deAngelo' (no middle name) will end up in 'nino.deangleo_AT_desy.de'.

Tip
titleHow do I change my email address in the collaboration email list?

The collaboration members email list is automatically created from the Belle II Membership Management System (B2MMS). Please change your email address there (see Belle II Membership Management System).

Tip
titleDo I have a DESY and belle2.org e-mail address?

The addresses are of the form 'firstname[.middlename].lastname_AT_desy.de' and 'firstname[.middlename].lastname_AT_belle2.org'. See Belle II email Addresses . The assigned address can also be found in your personal record in the Belle II membership management system.

Tip
titleWhat does PEM stand for?

'Privacy Enhanced Mail'. This is your 'real' personal email address with your mailbox behind.

Tip
titleI want to change my e-mail address?

Please send an email to  b2-helpdesk_AT_belle2.org.


Grid User Certificate and VO 'belle' membership (VOMS)


Tip
titleWhat are Grid certificates all about?

Please refer to the page What are Grid User Certificates . Note: Service or host certificates identify services and hosts not users!

Tip
titleAre there step-by-step instructions to obtain and use a Grid user certificate?

Please go to Belle II User Registration and scroll down.

Tip
titleI have already a Grid user certifcate?

Belle II collaborators who have a already a Grid user certificate and are already member of the VO 'belle' see Belle II User Registration. Make sure the Grid user certificate is in the browser!

Tip
titleI got my Grid user certificate in an e-mail?

You must copy the certificate part in the email into a file such as 'mycert.cer' and import this into your browser.

Tip
titleIs my Grid user certificate in the browser?

Check existence and validity of your Grid user certificate in your firefox browser in Preferences / Advanced / Certificates / View Certificates / Your Certificate.

Tip
titleI am confused about the name of the VO. Is it 'belle' or 'belle2.org'?

 For historic reasons the VO 'belle' is the correct one. Although this seems wrong, please do not use the VO 'belle2.org'.

Tip
titleAm I member of the VO 'belle'?

See https://voms.cc.kek.jp:8443/voms/belle .

Tip
titleWith my certificate I am already member of another VO?

The Grid user certificate allows to electronically prove your identity. This is independent of any VO membership though it can be used to gain membership one ore more VOs. 

Tip
titleI lost the password of my Grid user certificate?

 As the private key the password is as the the word implies 'private'. It is only known to you. Unfortunately you must request a new certificate from your CA.

Tip
titleHow to convert my KEK user certificate to .p12?

Please refer to this KEK manual.

Tip
titleI needed a .p12 cert for my browser but seem to have .p7b?

Please refer to https://www.sslshopper.com/ssl-converter.html for details.

Tip
titleHow to test my Grid user certificate in ~/.globus ?

Grid users usually have exported their Grid user certificate to ~/.globus to use it with Grid commands such as 'voms-proxy-init', 'dirac-proxy-init', or 'gb2_proxy_init'. The following commands may help to investigate the situation.

The directory:

> cd ~/.globus

> ls -l

-r--r--r-- 1  usercert.pem

-r-------- 1  userkey.pem


Checking if public (cert) and private (key) match:


> openssl x509 -noout -modulus -in usercert.pem | openssl md5
> openssl rsa -noout -modulus -in userkey.pem | openssl md5


Checking subject, issuer, and validity dates:

> openssl x509 -subject -issuer -email -dates -noout -in ~/.globus/usercert.pem


Recreating a single file with public and private key to be improted into a broser:

> openssl pkcs12 -export -out my_cert.p12 -inkey userkey.pem -in usercert.pem


Others (Browser cert problems, GIT/Stash, CAPTCHA)


Tip
titleMy browser complains about connection / SSL problems?

Connection errors such as 'SSL_ERROR_HANDSHAKE_FAILURE_ALERT' are due to old or missing CA certificates in your browser. You might want to check Preferences / Advanced / Certificates / View Certificates / Servers and Authorities . Also consider to use another browser. We have good experiences with firefox and we saw also safari on MAC working. From our experience there is usually someone in your group or institute who managed.

Tip
titleWhen trying to connect to the KEK VOMS server I see 'SSL_ERROR_HANDSHAKE_FAILURE_ALERT'?

In order to create the necessary secure connection to the KEK VOMS server, your browser needs to accept the VOMS server's certificate. Click 'Advanced' /  'Add exception' / 'Get certificate' / 'Store permanently' / 'Confirm' .

Tip
titleHow can I use my account with GIT/stash?

Please refer to Git/Introduction .

Tip
titleI see with git or stash: 'fatal: remote error: CAPTCHA required'?

You probably have typed in a wrong password to often. Now the system wants to make sure you are not a robot to reset the counter. Please try to log in to https://stash.desy.de and see the 'captcha' there and solve solve. If you are still logged in, log out completely first. Also make sure have not stored an old password in a script e.g. for git access!

Remember: Do NOT use your email address to log in, but your account name!

CAPTCHA stands for "Completely Automated Public Turing test to tell Computers and Humans Apart." It will ask you questions to find out whether you are real ...
