Hm. I am using Apache2 which, on Ubuntu Dapper 6.06, has mod_php_4. Both the
mysql_client and mysql_server packages are version 5.0.19, and I found it 
impossible
to downgrade to 4.1.x. As I see it, then, I can either install mod_php_5 and 
disable
mod_php_4, which should fix this problem, or I can start mysqld using the
--old-passwords directive. If I do that, and get rid of and then recreate the 
mail
database, are you saying that will also work? I don't mind whacking the database
since this is still a test server and there is nothing in it, and I don't 
really care
about the security associated with longer encrypted passwords, either. In fact, 
if I
do this, I suppose I could go all the way back to 'plain' instead of 'crypt' in 
the
web-cyradm config files. Oh, wait - that is a different password, right? (The 
users'
passwords as opposed to the password that WCA uses to log into the mail 
database..)

Anyway, which of the two methods is preferable? Some people said a day or so 
back
that they prefer php 4 as it seems to be faster than php 5.
