I have done everything I can to find documentation on where this error
comes from and how to fix it, however I cannot find anything. The
information I have found is that the time of the two servers has to be
more than 24 hours off in order for this to happen.  However my time is
well within the suggested limits.

Excessive clock skew between the supplier and the consumer. Replication
is aborting.

These two servers are setup in a multimaster configuration, contantly
replicating to each other.  Up until a week ago the servers had been
replicating without interruption for about at least a two month (I
started here a month ago) and now they do not seem to want to replicate
any more.  

 

I am new to LDAP in general, so if you need more information please let
me know what.

 

Thanks in advance.
