Performance
Related Information
|
This plug-in may
slow down Directory Server performance.
In a
multi-master replication
environment, the UID Uniqueness Plug-in will not work at all and should
therefore not be enabled.
If you try to
add a new entry to a
server where the UID Uniqueness Plug-in is enabled and a referral has
been created in a subtree, then the UID Uniqueness Plug-in will not
work because if it sees any other error apart from noSuchObject
(meaning that the entry does not already exist), which it will do if a
referral is created, then it will return an operations error preventing
you from adding your new entry. To prevent being blocked by such an
operations error, disable the plug-in on the server where you created
the referral. If, however, you still want to run a UID Uniqueness
check, make sure that you only activate the plug-in on the last of the
referred-to servers to prevent it from blocking the referral mechanism.
