Imp 2.2.7 login

[Paul Bauer]

I am trying to setup 2.2.7 for the moment,   I see that 3.0 is out
and in time I will upgrade

I do not undertstand the login process.   I have installed
horde/php3/imp and have gotten phplib to pass sessions to postgres.

When I goto login I see the attemp in my messages:
Jan 15 15:02:19 mail IMP[26715]: FAILED xxx.xxx.xxx.xxx to
mail.localhost.com:143 as pbauer

I see that the request has been sent to apache:
[15/Jan/2002:15:05:03 -0800] "GET
/horde/imp/login.php3?uniq=10676591263c44b59dbd07a HTTP/1.1" 200 7286
"http://localhost/horde/imp/" "Mozilla/5.0 (Macintosh; U; PPC Mac OS
X; en-US;v:0.9.5) Gecko/20011015"


but then it times out:
[15/Jan/2002:15:08:17 -0800] "GET
/horde/imp/login.php3?reason=timeout HTTP/1.1"200 7371
"http://localhost/horde/imp/login.php3?uniq=10676591263c44b59dbd07a"
"Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US; rv:0.9.5)
Gecko/20011015"
 
So what I would like help understanding is...
Where do the usernames and passwords reside?  Apache runs as user
nobody, postgres as pgsql and neither have permission to read
/etc/password.  So how do I pass valid users/passwords to imp?
I appreciate the pointer.
   Paul.

PS. FreeBSD 4.4-STABLE if it matters.
Again thank you.
