We have a cyrus server that's joined to an AD domain via winbind. Group enumeration and expansion is enabled inside winbind, so getgrent(3) delivers correct membership data for all groups. (Tested via getent group as well as a small C program just to make sure.) User A is in groups B and C; both have lowercase-only names without spaces or any other non-letter characters in them. If I use group:B in ACLs, A can access the mailbox. If I use group:C, A can't. It's a bit hard to pin down just what change could be responsible for this – the server was updated from wheezy to jessie to stretch in one migration, and to fix some unrelated Samba issues, group C had to be deleted and recreated (with the same name and GID and users and everything else getgrent cares about; it's working for file ACLs just fine and there's no difference in the getent group output to before). Any ideas where to look at for debugging this? -- Mit freundlichen Grüßen, / Best Regards, Sven Schwedas, Systemadministrator Mail/XMPP sven.schwedas@xxxxxx | Skype sven.schwedas TAO Digital | Lendplatz 45 | A8020 Graz https://www.tao-digital.at | Tel +43 680 301 7167 ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
