- * ldap_negotiated_sasl_bind_s - bind to the ldap server (and X.500)
- * using SASL authentication.
+ * ldap_sasl_interactive_bind_s - interactive SASL authentication
*
- * This routine attempts to authenticate the user referred by the
- * authentication id using the provided password. An optional
- * authorization identity may be provided. An DN is generally not
- * provided [see AuthMethod].
+ * This routine uses interactive callbacks.
*
- * If the mechanism negotiated does not require a password, the
- * passwd field is ignored. [A callback mechanism should really
- * be used].
- *
* LDAP_SUCCESS is returned upon success, the ldap error code
* otherwise.
- *
- * Examples:
- * ldap_negotiated_sasl_bind_s( ld, NULL,
- * NULL, NULL, NULL,
- * NULL, NULL, NULL, NULL );
