What't the syntax for performing a case-insensitive match on a 'uid' attribute? If attribute definition matters then how would that be changed? In particular I am using ApacheDS for my LDAP store.
(uid=miXedCaseUSer) will match a uid of mixedcaseuser.
Accoriding to the OID Description for 0.9.2342.19200300.100.1.1 - Userid userId is defined to have EQUALITY MATCHING RULE caseIgnoreMatch
Which means it is one of the attribute definitions that employ case insensitive matching by default.
I think they are case insensitive by default, unless its a password attribute.
