The pam_setcred() function is used to establish, modify, or delete user credentials. It is typically called after the user has been authenticated and after a session has been validated. See pam_authenticate(3PAM) and pam_acct_mgmt(3PAM).
The user is specified by a prior call to pam_start() or pam_set_item(), and is referenced by the authentication handle, pamh. The following flags may be set in the flags field. Note that the first four flags are mutually exclusive:
If no flag is set, PAM_ESTABLISH_CRED is used as the default.
Upon success, pam_setcred() returns PAM_SUCCESS. In addition to the error return values described in pam(3PAM) the following values may be returned upon error:
See attributes(5) for description of the following attributes:
pam(3PAM), pam_acct_mgmt(3PAM), pam_authenticate(3PAM), pam_set_item(3PAM), pam_start(3PAM), libpam(3LIB), attributes(5)
The interfaces in libpam are MT-Safe only if each thread within the multithreaded application uses its own PAM handle.
