Password sync for ldap users.
by saeed.s.jahromi＠gmail.com 02 Jul '22

02 Jul '22

Greetings, I have qluster 12 installed on a small HPC in our university. To create users remotely, I usually use the terminal and .ldif files to create users. I also use the following command to change users passwords from the terminal: ldappasswd -Z -D "cn=admin,dc=gavazang,dc=qlustar" -W -S "cn= saeed,ou=users,dc=gavazang,dc=qlustar" This works and the password is changed. However, the problem is that once in a while the user cant connect to the cluster and I have to reset the password again and again and this happens frequently. Should I do anything to sync the passwords after changing them? Or am I doing something wrong here? thanks in advance for your assistance

Qlustar Feature Update 06/22
by Qlustar List 28 Jun '22

28 Jun '22

A number of new Qlustar features were completed recently and published together with the latest security updates. QluMan 12.0.7.3 highly improves on its slurm management capabilities basically making the slurm component feature complete. It adds - Real SLURM QOS MANAGEMENT [1] in the GUI. QoS can now easily be added, edited, removed and assigned. The full list of QoS properties may be added/removed and manipulated including sanity checking the values entered. - SLURM ASSOCIATION AND LIMITS MANAGEMENT [2] has been added in the GUI unleashing the power of advanced slurm resource management to QluMan admins. Various visual filters have been created to achieve a comprehensive display of slurm associations. The full list of association settings may be added/removed and manipulated including sanity checking the values entered. * An 'LDAP GROUP <-> SLURM ACCOUNT' SYNC MECHANISM [3] has been designed to automate slurm user setup upon creation of the user in LDAP. Slurm accounts may be associated with LDAP groups such that depending on users primary group the corresponding slurm account will be assigned as their default. * Cron-based LDAP DB BACKUP was introduced to allow a disaster recovery in case the LDAP DB becomes corrupted. Other new features: - Update to AlmaLinux 8.6 [1] https://docs.qlustar.com/Qlustar/12.0/ClusterOS/qluman-guide/components/slu… [2] https://docs.qlustar.com/Qlustar/12.0/ClusterOS/qluman-guide/components/slu… [3] https://docs.qlustar.com/Qlustar/12.0/ClusterOS/qluman-guide/components/slu…

Using external LDAP server
by jan.kreps＠cvut.cz 13 Jun '22

13 Jun '22

Hello everyone, is there a way how to configure Qlustar to use external LDAP server instead of the one included in the installation? We run our own ldap server with passthrough authentication to Kerberos and want to use existing user accounts for Qlustar cluster as we did on our old cluster. Cheers, Jan

No Bootable Device Found during post install boot
by ignas.bunikis＠scilifelab.uu.se 07 Apr '22

07 Apr '22

Hej, I was attempting to install Qlustar using latest installer (Qlustar Installer 12.0.1-0) on a few years old SuperMicro server. Installation seemed to go smooth, but after first reboot popped up boot error message that no bootable devices were found. During another installation attempt I noticed a couple of error message: * Failed to fetch file ..postfix... Hash sum mismatch * Failed to fetch file ..python-slurm... Hash sum mismatch * Failed to fetch file ..python3-slurm... Hash sum mismatch AND *GRUB/10-setup FAILED with exit code 127 After that installer says: Good news! No errors found in log files Do you have any ideas what could be an issue and what to do? Cheers, Iggy
