How to create a user account (LDAP, SLURM, and SSL)

Short version

As an example we consider user ortiz:

• carme-manager --ldap-add-user
• carme-manager --slurm-add-user
• carme-manager --create-single-user-cert ortiz

Long version

In this example we considering that user christian ortiz is requesting a Carme account.

1) Using the bash script: carme-manager

All arguments of carme-manager are listed in: How to use the command: carme-manager (arguments).

Once the user is verified and we know what username to consider, we proceed with the following steps:

1. Access to Styx, e.g., ssh hades

2. carme-manager --ldap-add-user

   

   Fig. 6: LDAP account.

   
   

   In the above example we are creating an LDAP account ortiz in group (2): itwm-user.

   • A user password is generated. You should copy this password elsewhere for later use. In case you forget to do so, the password is stored in the file date--username.txt. To access this file type in styx: cd /root/ldap-default-passwds

3. carme-manager --slurm-add-user

   

   Fig. 7: SLURM account.

   
   

   We have:

   • ldap username: ortiz
   • slurm account: itwm-user
   • Admin or None: None
   • partition: carme
   • additional limitations: MaxJobs=4

4. for multiple users: carme-manager --create-user-certs

5. foe one user, e.g., user ortiz: carme-manager --create-single-user-cert ortiz

2) Without a bash script

The steps given in I.1) become:

1. ssh hades
2. cd /opt/Carme
3. cd Carme-Scripts/ldap
4. bash carme-ldap-add-user-sh (ldap account, refer to Fig. 6)
5. cd ../slurm/mgmt-scripts
6. bash carme-slurm-add-user.sh (slurm account, refer to Fig. 7)
7. cd /opt/Carme/Carme-Backend/SSL
8. bash create-and-deploy-user-certs.sh

If we want to modify something in slurm we do:

1. cd /opt/Carme
2. cd Carme-Scripts/slurm
3. bash carme-slurm-modify-user.sh
4. Enter what you want to modify, e.g.,: MaxJobs=1
