Ivano, I am running SSSD on the CES nodes (we need it for file authorization for NFS and SMB, but rely on AD for authentication). IBM set this up for us, had no issues doing it, and there were no library conflicts.

Our CES cluster is configured with the AD authentication and, accordingly to the documentation [1], SSSD should not be running on the CES nodes. For us that's quite annoying, ZjQcmQRYFpfptBannerStart External: Use caution with links, attachments, and providing information. <https://us-phishalarm-ewt.proofpoint.com/EWT/v1/MyIu0v6UfBA57LoN!4d_ODmlK7vdRO65GX_WTdZ3OfENAmlISr9BG6gKN6oPi384swmgkx0NzN8m6yWO08nZU-czK_NGKaSRNTtX3uO27nXLYetWX-fcXozmjTFNW7krLzXtpZD2eFFMkVMHiRpIuzzofs4dqbkJPXQ$> Report Suspicious <https://us-phishalarm-ewt.proofpoint.com/EWT/v1/MyIu0v6UfBA57LoN!4d_ODmlK7vdRO65GX_WTdZ3OfENAmlISr9BG6gKN6oPi384swmgkx0NzN8m6yWO08nZU-czK_NGKaSRNTtX3uO27nXLYetWX-fcXozmjTFNW7krLzXtpZD2eFFMkVMHiRpIuzzofs4dqbkJPXQ$> ZjQcmQRYFpfptBannerEnd Dear all, I have a question regarding the CES service, aka protocol nodes. Our CES cluster is configured with the AD authentication and, accordingly to the documentation [1], SSSD should not be running on the CES nodes. For us that's quite annoying, since we can't login with our personal/central accounts and then sudo. Neither we can use winbind, since samba-winbind-modules package (that provides the necessary PAM module) conflicts with the gpfs.smb package. We will probably end up creating one or more local accounts and using ssh keys for access. But I wonder if someone with a similar problem found a better workaround.
