NAME
pam_timestamp - Authenticate using cached successful authentication attemptsSYNOPSIS
- pam_timestamp.so [timestamp_timeout=number] [verbose] [debug]
DESCRIPTION
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
- How long should pam_timestamp treat timestamp as valid after their last modification date (in seconds). Default is 300 seconds.
verbose
- Attempt to inform the user when access is granted.
debug
- Turns on debugging messages sent to syslog(3).
MODULE TYPES PROVIDED
The auth and session module types are provided.
RETURN VALUES
PAM_AUTH_ERR
- The module was not able to retrieve the user name or no valid timestamp file was found.
PAM_SUCCESS
- Everything was successful.
PAM_SESSION_ERR
- Timestamp file could not be created or updated.
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
