NAME

       pam_sm_setcred - Service provider implementation for pam_setcred

SYNOPSIS

       [ flag ... ] file ...  [ library ... ]

DESCRIPTION

       In response to a call to the PAM framework calls from the modules listed in the pam.conf(4) file.  The authentication provider supplies the
       back-end functionality for this interface function.

       is called to set the credentials of the current user associated with the authentication handle, pamh.  The following flags may  be  set	in
       the flags field.  Note that the first four flags are mutually exclusive:

       Set user credentials for the authentication service.

       Delete user credentials associated with the authentication service.

       Reinitialize user credentials.

       Extend lifetime of user credentials.

       Authentication service should not generate messages.

       If none of these flags are set, is used as the default.

       The  argc  argument  represents	the number of module options passed in from the configuration file pam.conf(4).  argv specifies the module
       options, which are interpreted and processed by the authentication service.  If an unknown option is passed to the module, an error  should
       be logged and the option ignored.

       If the flag is not set, then should print any failure status from the corresponding function using the conversation function.

       The authentication status (success or reason for failure) is saved as module-specific state in the authentication handle by the authentica-
       tion module.  The status should be retrieved using and used to determine if user credentials should be set.

   Notes
       is passed the same module options that are used by

RETURN VALUE

       Upon successful completion, should be returned.	The following values may also be returned upon error:

       Underlying authentication service can not retrieve user credentials.

       User credentials have expired.

       User unknown to the authentication service.

       Failure in setting user credentials.

       Ignore underlying authentication module regardless of whether the
				     control flag is or
