Should I be having this issue on OpenLDAP 2.4.40? I have the filter

ldap:///?gidNumber?sub?(objectClass=posixGroup)

and cannot use gidNumber in posixAccount's. This was working in 2.4.31 if I recall correctly.

#!RESULT ERROR #!ERROR [LDAP: error code 19 - some attributes not unique] dn: cn=User Name,ou=People,dc=... changetype: modify replace: gidNumber gidNumber: 10000 -
