NAMEpam_setcred − establish / delete user credentials

SYNOPSIS#include <security/pam_appl​.h>int pam_setcred(pam_handle_t *pamh, int flags);

DESCRIPTIONThe pam_setcred function is used to establish, maintain and delete the credentials of a user​. It should be called to set the credentials after a user has been authenticated and before a session is opened for the user (with pam_open_session(3))​. The credentials should be deleted after the session has been closed (with pam_close_session(3))​. A credential is something that the user possesses​. It is some property, such as a Kerberos ticket, or a supplementary group membership that make up the uniqueness of a given user​. On a Linux system the user's UID and GID's are credentials too​. However, it has been decided that these properties (along with the default supplementary groups of which the user is a member) are credentials that should be set directly by the application and not by PAM​. Such credentials should be established, by the application, prior to a call to this function​. For example, initgroups(2) (or equivalent) should have been performed​. Valid flags, any one of which, may be logically OR'd with PAM_SILENT, are: PAM_ESTABLISH_CRED Initialize the credentials for the user​. PAM_DELETE_CRED Delete the user's credentials​. PAM_REINITIALIZE_CRED Fully reinitialize the user's credentials​. PAM_REFRESH_CRED Extend the lifetime of the existing credentials​.

RETURN VALUESPAM_BUF_ERR Memory buffer error​. PAM_CRED_ERR Failed to set user credentials​. PAM_CRED_EXPIRED User credentials are expired​. PAM_CRED_UNAVAIL Failed to retrieve user credentials​. PAM_SUCCESS Data was successful stored​. PAM_SYSTEM_ERR A NULL pointer was submitted as PAM handle, the function was called by a module or another system error occurred​. PAM_USER_UNKNOWN User is not known to an authentication module​.
