I don't know, what this specific error is, but in the dirsrv log, which 
seems to be from vm-244, we have:

set_krb5_creds - Could not get initial credentials for principal 
[ldap/vm-244.idm.lab.eng.brq.redhat.com at IDM.LAB.ENG.BRQ.REDHAT.COM] in 
keytab [FILE:/etc/dirsrv/ds.keytab]: -1765328228 (Cannot contact any KDC 
for requested realm)

so is your kdc running ?
