my thread got closed

I had a thread open and now it says it's closed. I had a question still on the forum and about 15mins after I posted my most recent question on it the thread said "closed". Why did this happen? I didn't violate any forum rules. Is there a limit on how many postings you can have in a single thread?... (1 Reply)

lchage - Display or change user password policy SYNOPSIS
lchage [OPTION]... user DESCRIPTION
Displays or allows changing password policy of user. OPTIONS
-d, --date=days Set the date of last password change to days after Jan 1 1970. Set days to -1 to disable password expiration (i.e. to ignore --mindays, and --maxdays and related settings). Set days to 0 to enforce password change on next login. (This also disables password expiration until the password is changed.) -E, --expire=days Set the account expiration date to days after Jan 1 1970. Set days to -1 to disable account expiration. -i, --interactive Ask all questions when connecting to the user database, even if default answers are set up in libuser configuration. -I, --inactive=days Disable the account after days after password expires (after the user is required to change the password). Set days to -1 to keep the account enabled indefinitely after password expiration. -l, --list Only list current user's policy and make no changes. -m, --mindays=days Require at least days days between password changes. Set days to 0 or -1 to disable this requirement. If this value is larger than the value set by --maxdays, the user cannot change the pasword. -M, --maxdays=days Require changing the password after days since last password change. Set days to -1 to disable password expiration. -W, --warndays=days Start warning the user days before password expires (before the user is required to change the password). Set days to 0 or -1 to disable the warning. EXIT STATUS
The exit status is 0 on success, nonzero on error. NOTES
Note that "account expiration" (set by --expire) is distinct from "password expiration" (set by --maxdays). Account expiration happens on a fixed date regardless of password changes. Password expiration is relative to the date of last password change. libuser Nov 8 2012 lchage(1)
