* ldap_negotiated_sasl_bind_s - bind to the ldap server (and X.500) |
|
* using 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]. |
|
* |
|
* 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, |
|
* "user@OPENLDAP.ORG", NULL, NULL, |
|
* "GSSAPI", NULL, NULL, NULL ); |
|

|
* "manager", "cn=user,dc=openldap,dc=org", NULL, |
