function ldap_badattr in Lightweight Directory Access Protocol (LDAP) 8.2

Same name and namespace in other branches

1. 7.2 ldap_servers/ldap_servers.functions.inc \ldap_badattr()
2. 7 ldap_servers/ldap_servers.functions.inc \ldap_badattr()

this attempts to find bad dns, but should only be used as warningswe as the ldap spec allows for any old character to be escaped and ldap implementations may not follow the spec.
