pam_succeed_if8Linux-PAMpam_succeed_iftest account characteristicspam_succeed_if.soflagconditionDESCRIPTION
pam_succeed_if.so is designed to succeed or fail authentication
based on characteristics of the account belonging to the user being
authenticated. 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.
OPTIONS
The following flags are supported:
Turns on debugging messages sent to syslog.
Evaluate conditions using the account of the user whose UID
the application is running under instead of the user being
authenticated.
Don't log failure or success to the system log.
Don't log failure to the system log.
Don't log success to the system log.
Conditions are three words: a field, a test,
and a value to test for.
Available fields are user,
uid, gid,
shell, home
and service:
Field has a value numerically less than number.
Field has a value numerically less than or equal to number.
Field has a value numerically less equal to number.
Field has a value numerically greater than or equal to number.
Field has a value numerically greater than number.
Field has a value numerically different from number.
Field exactly matches the given string.
Field does not match the given string.
Field matches the given glob.Field does not match the given glob.Field is contained in the list of items separated by colons.Field is not contained in the list of items separated by colons.User is in given group.User is not in given group.(user,host) is in given netgroup.(user,host) is not in given netgroup.MODULE SERVICES PROVIDED
All services are supported.
RETURN VALUESPAM_SUCCESS
The condition was true.
PAM_AUTH_ERR
The condition was false.
PAM_SERVICE_ERR
A service error occured or the arguments can't be
parsed as numbers.
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...
