Okay, it's me again. I don't know what was wrong with it, but now I can at least authenticate with an ad-hoc self-written C program, but there's a follow-up on that, I can't do pam_acct_mgmt() on any user; following error occurs: pam_acct_mgmt() error 9: Authentication service cannot retrieve authentication info Does this just mean that my backend doesn't support what pam_acct_mgmt() wants to do? _______________________________________________ Pam-list mailing list Pam-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/pam-list
