Good morning.
I have OpenLdap 2.4.12 and phpldapadmin 1.0.1.. My problem is occuring when i try register a new user. Follow error:
O servidor LDAP respondeu: Object class violation
Erro número: 0x41 (LDAP_OBJECT_CLASS_VIOLATION)
Descrição: You tried to perform an operation that would cause an undefined attribute to exist or that would remove a required attribute, given the current list of ObjectClasses. This can also occur if you do not specify a structural objectClass when creating an entry, or if you specify more than one structural objectClass.

And /var/log/messages:

Aug 10 07:58:11 webs slapd[3426]: Entry (cn=cyrusadmin cyrusadmin,ou=People,dc=novohamburgo,dc=rs,dc=gov,dc=br): object class 'posixAccount' requires attribute 'gidNumber'

This is stranger. In the PhpLdapAdmin, the fill gidNumber is blank, don't have option for change. What's happening ?
