[imp] Login.php problem with IMP, but all tests say OK (fwd)

[Hugh Hinskens]

I'm using Apache 1.3.26, IMAP 2001a, PHP 4.2.2, horde 2.1, and imp 3.1 on
OSF 4.0. I've followed all the installation and configuration instructions
and have the following problem:

When loading login.php, I get two errors in my apache logs:

[error] PHP Notice: Undefined index: alternate_login in
/home/local/apache/share/htdocs/horde.new/imp/login.php on line 89
[error] PHP Notice: Undefined index: server in
/home/local/apache/share/htdocs/horde.new/imp/login.php on line 135

I have $conf['user']['alternate_login'] = 'false'; in conf.php, and have
configured the lines for imap in servers.php. If I try to login, It
reloads login.php and repeats the above two errors. I've tested
everything I can with the tests in "5.2 Verifying Components" of the admin
FAQ and all the tests come up OK. Thanks.
