All, Users are complaining when they change their passwords in AD, it's taking an excessive amount of time to be reflected on their sssd-integrated Linux servers. Temporarily, they are denied access to their boxes.
These are boxes they log into frequently, so I'm guessing their Posix attributes are read from cache. (Does this include their password)? I'm setting only these cache settings in the sssd.conf file: [nss] entry_cache_nowait_percentage = 75 ... [domain/xxx] ... cache_credentials = True Here's the entry that's being reported (in /var/log/secure). The user reports that he waits 15 - 20 mins after changing his password in AD before attempting to ssh in: Oct 21 19:50:16 acmappdev01 sshd[9817]: pam_sss(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=10.185.116.129 user=gudar1 Oct 21 19:50:16 acmappdev01 sshd[9817]: pam_sss(sshd:auth): received for user gudar1: 6 (Permission denied) After 20 - 30 mins, the problem goes away without any intervention. Oct 21 20:15:40 acmappdev01 sshd[11326]: pam_sss(sshd:auth): authentication success; logname= uid=0 euid=0 tty=ssh ruser= rhost=10.185.116.129 user=gudar1 Oct 21 20:15:40 acmappdev01 sshd[11326]: Accepted password for gudar1 from 10.185.116.129 port 49954 ssh2 I realize it can take up to 30 mins for a changed password to fully replicate in AD globally. But what settings in sssd determine how long passwords are stored in cache? I see entry_cache_timeout, which has a default of 5400 seconds. (1.5 hrs). Should I set entry_cache_user_timeout to something lower -- say 15 mins? Spike
