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.
