Finding source code for login

I set

"user1 hard maxlogins 2"

i found "logged in as user1 twice" While logging for third time it said "Too many logins" - So i logged out "logout" from previous two logins ...even now it says the same error msg

I can verify this using "who" command running as root and check pam.d/login looks fine too.

I think ,its bug with login binar开发者_JS百科y where can i found source for both login and limits.conf

On my ubuntu system:

apt-file search /bin/login

gives:

gforge-web-apache2: /usr/share/gforge/www/scm/viewvc/bin/loginfo-handler
login: /bin/login
userful-multiplier: /opt/userful/bin/login-server

so, on debian based distros, you can get the source for the "login" package:

apt-get source login

Edit Seems the actual package name is "shadow".
