Hello !
I recently installed a replica (master2) in addition of my master
(master1) with IPA 3.0.0-47 on RHEL6.6.
I don't know from when exactly, but the dirsrv (and the whole ipa
service) on master1 crashes regularly with the following logs.

Then the dirsrv, I mean the whole ipa server, is down.
When I restart the service, here is what is see :

It seems that there is a problem to write an entry in the DB ? Do you
know how I can solve this problem please ?
Furthermore, it seems that there is a second problem with the keytab
/etc/dirsrv/ds.keytab.
The keytab is good for me :
###
#ls -l /etc/dirsrv/ds.keytab
-rw------- 1 dirsrv dirsrv 362 Jan 21 14:12 /etc/dirsrv/ds.keytab
# kinit -kt /etc/dirsrv/ds.keytab ldap/<master1>@<myrealm>
# klist
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: ldap/<master1>@<myrealm>
Valid starting Expires Service principal
01/25/16 11:54:23 01/26/16 11:54:23 krbtgt/<myrealm>@<myrealm>
###
I wonder if this second problem does not come from the user dirsrv who
would not be able to use this keytab.
I cannot test this because this user dirsrv has been created with nologin.
###
# su - dirsrv -c "kinit -kt /etc/dirsrv/ds.keytab
ldap/<master1>@<myrealm>"
This account is currently not available.
# grep dirsrv /etc/passwd
dirsrv:x:244:497::/var/lib/dirsrv:/sbin/nologin
pkisrv:x:246:497::/var/lib/dirsrv:/sbin/nologin
###
Just for my information, is it normal that these users are created
with nologin ?
Best regards.
