Hi,
First off, many thanks Roland for your earlier help with the Qlustar 12.0 installer. We've been up and running for a few months now and have almost everything working as desired.
I'm writing because I have a few questions both about some issues we have not been able to resolve and some introduced in the latest security updates (QSA-0903211 and QSA-0903212).
Latest issues first:
1. Since installing the latest security updates a few days ago I have noticed that Slurm has stopped working and the qluman-qt 'Components' option is grayed out (see https://imgur.com/a/W1Ejsvn). I'm not totally sure what the issue might be, but I noticed that the slurmdbd and slurmctld services are not running on the head node, and in fact are masked, which I understand will stop them from starting, right? You can see the output from 'service --status-all' and 'systemctl list-unit-files --state=masked' below. Any suggestions about how to re-enable Slurm?

2. In addition to the Slurm issue, I have also not been able to create new user accounts because the 'Components' option in qluman-qt is grayed out. I have previously migrated our old NIS user accounts to LDAP, but I am lackign experience with LDAP and unsure how to explore this issue.
And finally, one older issue we have not resolved:
3. How do you change user passwords for LDAP users in Qlustar 12? I had been able to generate new passwords in qluman, but have not been able to figure out how what users should do to update their passwords. It seems perhaps there is a lifetime to the autogenerated passwords, so I have manually reset passwords when users needed them. Obviously, this is not something that is good in the long run. Do you have a suggestion?
And sorry for the compilation of questions above. Hopefully the fixes are obvious to you and not too much trouble.
Best, Dave
