It does so by prompting the user for his password and then ensures +that it's correct using +.BR crypt (3). +.PP +The account management routine performs a series of tests to verify whether +the authenticated user is allowed access to the local user account by checking +the following +.BR shadow (3) +elements: expire, last_change, max_change, min_change, warn_change. If the +*_change elements are set the user will be informed in case the account is +about to expire and if it has expired already, access will be denied +for that user. +.PP +The password management routine is responsible for updating a user's password +entry in +.BI /etc/passwd +and in +.BI /etc/shadow +(the latter only in case the shadow flag is set). +.SH OPTIONS +.PP +.IP \fBdebug\fR +Produce syslog debug messages (this is silently ignored as it's the default behaviour). +.IP \fBmd5\fR +Use md5 hashes for user passwords instead of the default DES +.IP \fBnullok\fR +Allow null passwords. +.IP \fBsha512\fR +Use sha512 hashes for user passwords instead of the default DES (not yet supported). +.SH FILES +.I /etc/pam.d/login +.RS + The PAM configuration file for the login utility. +.RE +.PP +.I /etc/pam.d/passwd +.RS +The PAM configuration file for the passwd utility. +.RE +.PP +.I /etc/pam.d/su +.RS +The PAM configuration file for the su utility +.RE +.PP +Similar files exist for all applications who make use of the PAM modules and all of +them reside in +.I /etc/pam.d/ +.SH AUTHOR +Seraphim Mellos <mellos at ceid dot upatras dot gr> +.SH "SEE ALSO" +.BR passwd (1), +.BR login (5), +.BR su (1), +.BR pam (8), +.BR pam.conf (8) |
