[Freeipa-users] IPA client randomly lose memory of users

2012-11-30 Thread Qing Chang

my dovecot IMAP server would randomly lose memory of users, as an example:

Samba/NFS server knows this user:
[root@smb2 shassan]# getent passwd bqiang
bqiang:*:47105:471:Beiping Qiang:/home2/bqiang:/bin/tcsh

But dovecot server does not:
[root@dovecot2 ~]# getent passwd bqiang

Only when I apply this:
[root@dovecot2 ~]# \rm /var/lib/sss/db/cache_sri.utoronto.ca.ldb
[root@dovecot2 ~]# service sssd restart

It gets it:
[root@dovecot2 ~]# getent passwd bqiang
bqiang:*:47105:471:Beiping Qiang:/home2/bqiang:/bin/tcsh

So far I have to deal with this for three users. It's quite possible
that there are more than 3 that are affected, they were just patient
enough to wait until dovecot recovers its memory.

Again, this seems to be a sssd bug?

Thanks,
Qing

Seems like it. I'd go ahead and file a bug against sssd to get the ball 
rolling.


If you can enable sssd debugging and catch the case where a user is lost 
I'm sure that would be very helpful to the sssd team.
