Hi Diego, the submission process runs on the slurmctld, so the user must be known there.

Being a message generated by slurmctld, I thought it must be the frontend node. But, as I wrote, that system correctly identifies the user (he's logged in, 'id' and 'getent passwd' can resolve both the name and the UID).If you are part of a domain or other shared directory (ldap, etc), your master is likely not configured right.The frontend is an AD member, using PBIS-open. It's been working as-is for at least the last 6 years :) and other users from the same domain are able to submit jobs.If you are using SSSD, it is also possible your sssd has too long of a cache time. Run "sss_cache -E" to clear everything.To partially workaround an issue with conflicting UIDs/GIDs (the PBIS-assigned range is too short for our forest), I already clear the PBIS cache every 5 minutes and re-populate it forcing an id of every entry of /home/{PERSONALE,STUDENTI}/*.* entry (this forces PBIS to pull the right name from AD when first resolving the UID, so the GUID is already cached and associated to the UID when the reverse mapping is required).If you have a forest, it could be the information has not propagated to all the servers, so you have to wait. I've been places where that can take 24 hours.It's been more than a week since the first failure :( And our forest usually propagates changes in just a few minutes (more often in seconds).
