How work the roundcube login page ?

[falirki08]

Hi everybody,

I wonder if someone have a little time for explain me how work the part of the login in roundcube.

I would like to understand how and where (wich part of file) roundcube is checking the user name and password.

And also where and how did the redirection on the page mail.html after successful authentication.

My goal also is to eventually add a check for more, like allowing the users in the group who are "authorized" to log in roudcube

Thank you in advance for your reply
(sorry for my english)

Regards
