[Samba] LDAP mismatch between DCs

[John Gardeniers]

Running "samba-tool ldapcmp ldap://DC1 ldap://DC2 -Uadministrator" on 
our production system results in mismatches for items in the domain section:

* Comparing [DOMAIN] context...

* Objects to be compared: 625

Comparing:
'CN=AdminRole,OU=Group,OU=Postgres,DC=ourdomain' [ldap://DC1]
'CN=AdminRole,OU=Group,OU=Postgres,DC=ourdomain' [ldap://DC2]
     Difference in attribute values:
         whenChanged =>
['20160111045058.0Z']
['20160111045103.0Z']

This is repeated for all other entries in the section, although the 
timestamps differ. All other sections match perfectly.

Is this something to be concerned about or can it be safely ignored?

regards,
John
