 PAM_UNIX_SESSION 7 "August 19, 2023"
 NAME
pam_unix_session - PAM session management module for UNIX
 SYNOPSIS
pam_unix_session.so.1


 DESCRIPTION
The pam_unix_session module implements pam_sm_open_session(3PAM)
and pam_sm_close_session(3PAM).

pam_sm_open_session() updates the /var/adm/lastlog file with the
information contained in the PAM_USER, PAM_TTY, and
PAM_RHOSTS items. pam_unix_account(7) uses this account to
determine the previous time the user logged in.

pam_sm_close_session() is a null function.

The following options can be passed to the module:
debug

syslog(3C) debugging information at the LOG_DEBUG level


nowarn

Turn off last login PAM_TEXT_INFO message.


 ERRORS
Upon successful completion, PAM_SUCCESS is returned. The following error
codes are returned upon error:
PAM_SESSION_ERR

Cannot make or remove the entry for the specified session (PAM_TTY is not
present).


PAM_USER_UNKNOWN

No account is present for user.


 ATTRIBUTES
See attributes(7) for descriptions of the following attributes:

The interfaces in libpam(3LIB) are MT-Safe only if each thread within the
multi-threaded application uses its own PAM handle.

The pam_unix(7) module is no longer supported. Similar functionality is
provided by pam_authtok_check(7), pam_authtok_get(7),
pam_authtok_store(7), pam_dhkeys(7), pam_passwd_auth(7),
pam_unix_account(7), pam_unix_auth(7), and
pam_unix_session(7).
