LDAP identifier is not compatible with php 8.3

[doshu]

in php 8.3 ldap_connect function throw a deprecated warning if used with the signature $host, $port instead of $dsn

LDAP identifier set a custom error handler for catching ldap error enf throw an exception.

inthis way the deprecated warning is converted in an exception
