[horde] No supported IMAP authentication method could be found

[Lee Evans]

Hi,

Firstly thanks to those who helped out with my last query with regards LDAP
hooks - I now have this working.

I understand HTML signatures are supported in IMP 4.1 which [unfortunately]
is something I could really do with.

I've tried to upgrade IMP to 4.1 from 4.0.4 but now when I log in I receive
the error:

"No supported IMAP authentication method could be found"

This only happens when correct credentials are supplied, else it says
Authentication Failed - so it must be talking to the IMAP server at some
point.

The httpd error log shows the following:

[client 192.168.1.114] PHP Notice:  Undefined index:  notepad in
/usr/share/horde/imp/lib/Session.php on line 232

And the same with regards 'Virtual Folders' - I guess this is just due to a
mismatch with the configuration I've copied from my old install, but as
they're only Notices I wouldn't have thought this is a major problem.

Can anyone suggest where I might look for the offending issue?

Thanks
Lee
