Nah... "" and NULL (and I suppose "\0") are all being changed to the string "" before PHP attempts to add it. What I think the LDAP server tries to say, is that the syntax doesn't accept an empty string as value. I tried to create an LDIF file containing an attribute with no value, like this: dn: cn=stig,o=photos,dc=venaas,dc=no objectClass: photo cn: stig description: and I got exactly the same error from ldap_add(1). So this is in my opinion an LDAP issue and not a PHP issue. OpenLDAP 2 has more proper schema checking. Perhaps you could try to turn off schema checking? Or I guess in theory the syntax for the relevant attribute could be made more relaxed. You could try to ask about this on the openldap-software list if you need more LDAP help. Stig
