Removal of an attribute from the list of unique attributes
To remove an attribute from the list of unique attributes, you can use the Web Administration tool or the command line.
Note: If a unique attribute exists in both
cn=uniqueattributes,cn=localhost and cn=uniqueattributes,cn=IBMpolicies and
it is removed from only one entry, the server continues to treat that
attribute as a unique attribute. The attribute becomes non-unique
when it is removed from both entries.
