OpenLDAP "pwdPolicySubentry" for ppolicy not applying
I'm trying to get ppolicy to work on a CentOS 5.6 server I have at home running OpenLDAP 2.3.43. I cannot get pwdPolicySubentry to show up as an available attribute for any user (using ldapadd with LDIF (doesn't error, but attribute does not get applied) or programs such as JXplorer or Apache Directory Studio). I'm able to add pwdPolicy and pwdPolicyChecker as classes, but they don't appear to contain the "pwdPolicySubentry" I desire.
I have the following relevant items in my slapd.conf:
I googled around and took a look at /etc/openldap/schema/ppolicy.schema and noticed that the section for pwdPolicySubentry was commented out within the schema file. I tried removing the leading #'s but this did not improve my luck.
Any insight is very much appreciated. Thank you.
