Modifying/Deleting Users

[icermccate]

I attempted to add a user with a key, and citc responded with "ldap_add: Already exists (68)"

I tried to remove the user, and citc responded with "ldap_bind: Server is unwilling to perform (53)
additional info: Unauthenticated binds are not allowed"

The remove command I used was ldapdelete -v -c -D "cn=user_name,ou=People,dc=citc,dc=acrc,dc=bristol,dc=ac,dc=uk"

What am I doing incorrectly?
