[imp] Problem with H4 IMP Dynamic mode

[Eric Rostetter]

I installed H4 and was testing it.  All seems good in traditional  
mode.  I can use traditional mode IMP
without any problems at all.  But, as soon as I switch to Dynamic  
Mode, IMP can no longer access my inbox.

Authentication via IMP still works, sending still works (I'm sending  
this message via H4 IMP in dynamic mode),
but when I try to see my inbox it pops the following errors on the screen:

Error when communicating with the server.
Error when communicating with the server.
The server was unable to generate the message list.
The server was unable to generate the message list.

The only error log entry I can find is from apache, which complains:

PHP Fatal error:  session_start() [<a  
href='function.session-start'>function.session-start</a>]: Failed to  
initialize storage module: user (path: /var/lib/php/session) in  
/httpd/horde4/pear/php/Horde/Session.php on line 150, referer:  
https://mail.ph.utexas.edu/test/imp/

Any ideas what could be causing this problem in Dynamic but not  
Traditional IMP?
