Good day to everybody.

I'm trying to add a new schema inside OpenLDAP. But getting an error:

ldap_add: Insufficient access (50)

root@ldap:/# ldapadd -c -x -D cn=admin,dc=domain,dc=com -W -f /tmp/test.d/cn\=config/cn\=schema/cn\=\{5\}microsoft.ldif

 e ) MAY ( primaryGroupToken $ memberOf $ primaryGroupID ) )

I also tried to add the schema by phpldapadmin, but gain the same error.

I'm using the admin user which is specified by default from the begging of the slpad installation. How may I add permissions to this user ?

Best wishes
