Имя (Name)

pam_succeed_if - test account characteristics

Синопсис (Synopsis)

pam_succeed_if.so [flag...] [condition...]

---

Описание (Description)

pam_succeed_if.so is designed to succeed or fail authentication
       based on characteristics of the account belonging to the user
       being authenticated or values of other PAM items. One use is to
       select whether to load other modules based on this test.

       The module should be given one or more conditions as module
       arguments, and authentication will succeed only if all of the
       conditions are met.

Параметры (Options)

The following flags are supported:

       debug
           Turns on debugging messages sent to syslog.

       use_uid
           Evaluate conditions using the account of the user whose UID
           the application is running under instead of the user being
           authenticated.

       quiet

       field eq number
           Field has a value numerically equal to number.

       field >= number
           Field has a value numerically greater than or equal to
           number.

       field > number
           Field has a value numerically greater than number.

       field ne number
           Field has a value numerically different from number.

Возвращаемое значение (Return value)

PAM_SUCCESS
           The condition was true.

       PAM_AUTH_ERR
           The condition was false.

       PAM_SERVICE_ERR
           A service error occurred or the arguments can't be parsed

Примеры (Examples)

To emulate the behaviour of pam_wheel, except there is no
       fallback to group 0:

           auth required pam_succeed_if.so quiet user ingroup wheel

       Given that the type matches, only loads the othermodule rule if
       the UID is over 500. Adjust the number after default to skip
       several rules.

           type [default=1 success=ignore] pam_succeed_if.so quiet uid > 500
           type required othermodule.so arguments...
