PAM_TIMESTAMP(8) | Linux-PAM Manual | PAM_TIMESTAMP(8) |
NAME¶
pam_timestamp - Authenticate using cached successful authentication attempts
SYNOPSIS¶
pam_timestamp.so [timestamp_timeout=number] [verbose] [debug]
DESCRIPTION¶
In a nutshell, pam_timestamp caches successful authentication attempts, and allows you to use a recent successful attempt as the basis for authentication. This is similar mechanism which is used in sudo.
When an application opens a session using pam_timestamp, a timestamp file is created in the timestampdir directory for the user. When an application attempts to authenticate the user, a pam_timestamp will treat a sufficiently recent timestamp file as grounds for succeeding.
OPTIONS¶
timestamp_timeout=number
verbose
debug
MODULE TYPES PROVIDED¶
The auth and session module types are provided.
RETURN VALUES¶
PAM_AUTH_ERR
PAM_SUCCESS
PAM_SESSION_ERR
NOTES¶
Users can get confused when they are not always asked for passwords when running a given program. Some users reflexively begin typing information before noticing that it is not being asked for.
EXAMPLES¶
auth sufficient pam_timestamp.so verbose auth required pam_unix.so session required pam_unix.so session optional pam_timestamp.so
FILES¶
/var/run/sudo/...
