Ldap sasl bind(gssapi problem)

Hallo there everyone,
after finishing my server side configuration so as to have the
maximum security
i tried this morning to do a sasl bind with my ldap server ,
my file looks like that:

*$ldapbind=ldap_sasl_bind($ldapconn,NULL,NULL,"GSSAPI","TEIPIR.GR
","ldapmaster","dn:[email protected],ou=kerberos,dc=teipir,dc=gr");*
*    // verify binding*
*
*
*   ** ** if ($ldapbind) {*
*        echo "LDAP bind successful..." . "<br />";*
* *
every other mech i use seems to work fine but only the gssapi is not
workign from what i can see on the log
i have tried most of the additional commands i found on the net like:

putenv("KRB5CCNAME={$_SERVER['KRB5CCNAME']}");



*but still nothing *
*any idea to make the bind over gssapi so as to have the kerveros ticket
exchange actually working*
*
*
*Thank you *
