[horde] Store TOS information in database

[Felipe Scarel]

Hey there guys,

I'm configuring a Horde installation for my employer and have stumbled upon
a problem. I'm using the TOS Agreement feature from Horde to display a TOS
to my users, and only let them log in if accepted. To achieve that I'm using
the 'imap' auth driver directly in Horde, and 'hordeauth = true' in IMP.
Users are logging in just fine, and the TOS works as intended.

I don't know that much PHP, but what I've understood from
'lib/LoginTasks/Task/TosAgreement.php' is that it checks for the acceptance
of the TOS somewhere in client-side (using 'Horde_Util::getFormData', I
think). That seems to be the case, since I ran some tests and, after
clearing browser cache, the TOS shows up again for a user that had accepted
it in the past.

My question is: I'd like to store the TOS acceptance in the Horde MySQL
database (or the LDAP db against which my IMAP auths are checked, either is
fine), preferably as a timestamp registering when the user accepted the TOS.
Is there any easy/standard way of doing that in Horde, or I'd have to go
about changing 'lib/LoginTasks/Task/TosAgreement.php'? If changes are
needed, would they persist through upgrades?

Oh yes, and I'm running the most recent Horde release... just ran a 'pear
upgrade' on my server.

Cheers and thanks in advance,
