HP-UX Directory Server 8.1 deployment guide

consistency in replicated schema allows replication to continue smoothly. Consider the following
points for maintaining consistent schema in a replicated environment:
• Do not modify the schema on a read-only replica.
Modifying the schema on a read-only replica introduces an inconsistency in the schema and
causes replication to fail.
• Do not create two attributes with the same name that use different syntaxes.
If an attribute is created in a read-write replica that has the same name as an attribute on
the supplier replica but has a different syntax from the attribute on the supplier, replication
will fail.
