Martin,

	Very, very strange.  The only things I can suggest are checking your 
error_log for more details to see if there is a bad entry somewhere.  
Also checking the .htaccess and httpd.conf setup to make sure they are 
working fine. Another thing to check (just to be on the safe side) is to 
make sure that mod_gzip is the LAST entry in the module list.  From the 
module listing you gave me it doesn't look like it is... the last loaded 
module shows first on the list when in the loaded modules blurb (If I 
remember correctly).  
	I have been using .htaccess files with the PosgreSQL database 
authentication module on our server for a long time and have not seen 
this problem.  Could it maybe, possibly be something to do with using PAM 
authentication?  For the record the URL you sent comes up with "This page 
cannot be displayed" and doesn't even offer me a login prompt in IE 5.5 
on Win98SE so I would check your error logs.
	Hopefully we can figure out the problem for you.

Tim Frank
