It is typically called after the user has been authenticated and after a session has been validated. See \fBpam_authenticate\fR(3PAM) and \fBpam_acct_mgmt\fR(3PAM). .sp .LP The user is specified by a prior call to \fBpam_start\fR(3PAM) or \fBpam_set_item\fR(3PAM), and is referenced by the authentication handle, \fIpamh\fR. The following flags may be set in the \fIflags\fR field. Note that the first four flags are mutually exclusive: .sp .ne 2 .mk .na \fB\fBPAM_ESTABLISH_CRED\fR\fR .ad .RS 25n .rt Set user credentials for an authentication service. .RE .sp .ne 2 .mk .na \fB\fBPAM_DELETE_CRED\fR\fR .ad .RS 25n .rt Delete user credentials associated with an authentication service. .RE .sp .ne 2 .mk .na \fB\fBPAM_REINITIALIZE_CRED\fR\fR .ad .RS 25n .rt Reinitialize user credentials. .RE .sp .ne 2 .mk .na \fB\fBPAM_REFRESH_CRED\fR\fR .ad .RS 25n .rt Extend lifetime of user credentials. .RE .sp .ne 2 .mk .na \fB\fBPAM_SILENT\fR\fR .ad .RS 25n .rt Authentication service should not generate any messages. .RE .sp .LP If no flag is set, \fBPAM_ESTABLISH_CRED\fR is used as the default. .SH RETURN VALUES .sp .LP Upon success, \fBpam_setcred()\fR returns \fBPAM_SUCCESS\fR. In addition to the error return values described in \fBpam\fR(3PAM) the following values may be returned upon error: .sp .ne 2 .mk .na \fB\fBPAM_CRED_UNAVAIL\fR\fR .ad .RS 20n .rt Underlying authentication service can not retrieve user credentials unavailable. .RE .sp .ne 2 .mk .na \fB\fBPAM_CRED_EXPIRED\fR\fR .ad .RS 20n .rt User credentials expired. .RE .sp .ne 2 .mk .na \fB\fBPAM_USER_UNKNOWN\fR\fR .ad .RS 20n .rt User unknown to underlying authentication service. .RE .sp .ne 2 .mk .na \fB\fBPAM_CRED_ERR\fR\fR .ad .RS 20n .rt Failure setting user credentials. .RE .SH ATTRIBUTES .sp .LP See \fBattributes\fR(7) for descriptions of the following attributes: .sp .TS tab( ) box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) . ATTRIBUTE TYPE ATTRIBUTE VALUE _ Interface Stability Committed _ MT-Level MT-Safe with exceptions .TE .sp .sp .LP The interfaces in \fBlibpam\fR are MT-Safe only if each thread within the multithreaded application uses its own \fBPAM\fR handle. .SH SEE ALSO .sp .LP \fBlibpam\fR(3LIB), \fBpam\fR(3PAM), \fBpam_acct_mgmt\fR(3PAM), \fBpam_authenticate\fR(3PAM), \fBpam_set_item\fR(3PAM), \fBpam_start\fR(3PAM), \fBattributes\fR(7) .SH HISTORY .sp .LP The \fBpam_setcred()\fR function was introduced in Solaris 2.6.
