[imp] Weird Problem

[Hammad]

Hello guys:

I have a problem, since I am using both Horde & IMP I am not sure which one
messing it up. I think its more towards horde. I am an old user of Horde 2 and
IMP 3.

I decided to test new stable versions of Horde 3.0.4/IMP 4.0.3. Things looked
good , it connects to Mysql(4.0.21-4.4) database, IMP connects to Courier-IMAP
server until I go in 'Admin'/'Setup' menu for Horde and select 'SQL' for Horde
preference. Once I click on 'Generate', I start getting error messages
----------------------------
Jun 02 00:49:31 HORDE [emergency] [] DB Error: connect failed: 
[nativecode=Can't connect to local MySQL server through socket
'/var/lib/mysql/mysql.sock' (13)] ** Array [on line 378 of
"/var/www/horde.prod/horde/lib/Horde/Prefs/sql.php"]
Jun 02 00:54:31 HORDE [emergency] [] DB Error: connect failed: 
[nativecode=Can't connect to local MySQL server through socket
'/var/lib/mysql/mysql.sock' (13)] ** Array [on line 378 of
"/var/www/horde.prod/horde/lib/Horde/Prefs/sql.php"]
-----------------------------

The only way I can fix it is either by recopying horde/config/conf.php.dist or
by removing config enteries for horde [prefs]. Now this also happens if I
select 'SQL' for datatree, Virtual File storage, custom session handler etc.

Any idea?
