[horde] Programming question

[Barsalou]

The file format of the ecartis file is:

username at example.com : |flag1|flag2|flagn|

My question revolves around the username portion.  If I try to login
with username at example.com, will it strip the example.com off by default?

If that is true, then I will probably need to write a custom hook for
the login, right?

The idea is to use the Ecartis maillist program's information to
authenticate for horde to give access to a shared calendar to the list
member's.

The goal is to allow the group to use Kronolith and Wiki features of
Horde only. Maybe other features in the future.

Does anyone have any other suggestions on how to possibly implement
this?

Using current CVS.
