The nscd profile allows reading and writing the /var/lib/nscd/ files you mentioned (and does so since a long time IIRC), therefore I'm surprised why you get denials for them.

Can you please check if you have some *.rpmnew files in /etc/apparmor.d/ ?

No I do not have these files. After a reboot just now I do not see these DENIED in the log file.

For the dovecot issues, please edit /etc/apparmor.d/usr.lib.dovecot.auth and add the following two lines:

capability dac_read_search, capability dac_override,

(You can instead add them to /etc/apparmor.d/local/usr.lib.dovecot.auth if you prefer not to edit rpm-managed files.)

Done

Afterwards, run rcapparmor reload to reload all profiles.

No DENIED since the last reboot.

Note to myself: /var/spool/postfix/private/ (postfix:root 700) might be the reason for dac_read_search, and /run/dovecot/auth-worker (dovecot:root 600) is probably a reason for dac_override.

Indeed these are the protection masks on this directory, respectively socket. -- You are receiving this mail because: You are on the CC list for the bug.

nov 25 12:03:08 eiktum auth[6627]: pam_kwallet5(dovecot:auth): pam_kwallet5: Fail into creating the hash

I'm not sure what kwallet tells you with this error message, but it's probably unrelated (I'd _guess_ it happens when fetching the password from the wallet, before using it for imap login)

nov 25 12:03:08 eiktum dovecot[2008]: imap-login: Login: user=<freek>, method=PLAIN, rip=::1, lip=::1, mpid=6629, secured, session=<0QdHncxeqqEAAAAAAAAAAAAAAAAAAAAB>

That looks like a successful imap login.

nov 25 12:04:09 eiktum dovecot[1640]: master: Error: service(auth): kill(3207, SIGINT) failed: Permission denied

Might be a missing signal rule, but (assuming my guess is right) you should see DENIED messages for it in audit.log. If you see this again, please check (using ps Zaux) which process is running under the mentioned pid (3207 in your log line). Hmm, maybe you hit bug 1069562. The kernel with the fix is currently building in Kernel:HEAD - feel free to test as soon as 4.14.2 appears on http://download.opensuse.org/repositories/Kernel:/HEAD/standard/ -- You are receiving this mail because: You are on the CC list for the bug.

(In reply to Freek de Kruijf from comment #8) Which kernel version do you use?

As I already mentioned in a previous comment, 4.14.0 and 4.14.1 have a known bug, so please use 4.14.2 (from Kernel:HEAD until it reaches Tumbleweed).

I wouldn't be surprised if you have the broken kernel, and this is a side effect of that bug. (Nevertheless, the dovecot profile might need some signal rules added - but for sure not for rtmin+772495128 ;-)

I now have 4.14.2 running and DENIED messages are gone. Although I also have: eiktum: # more /etc/apparmor.d/local/usr.sbin.dovecot # Site-specific additions and overrides for 'usr.sbin.dovecot' capability dac_read_search, # capability dac_override, like you suggested below.

...

That means the dovecot profile (/etc/apparmor.d/local/usr.sbin.dovecot) needs (probably because /var/spool/postfix/private/ is postfix:root 700) capability dac_read_search,
