For archival purposes on this list.. I ended up using another schema file of:
# Attribues start here
attributetype (1.3.6.1.4.1.11048.1.1.1.11 NAME 'custID' EQUALITY caseExactMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 DESC 'Unique ID value to identify a specific customer' )
Why don't you use uid? uid==Unique Identifier.
