[Web-cyradm] Free form usernames, 0.5.3->0.5.4 and Debian

[GnomeKing]

Hey guys, 

I'm using debian and followed the how to at 
http://web-cyradm.org/debian/HowTo.txt to install web-cyradm to be used as a 
single domain family email server - with a simple configuration tool for my 
parents to use!

Although there are several improvements which I think could be made to the how 
to (e.g., all /var/run lines should be changed in the my.cnf, and the how-to 
asks you to use the insertuser_mysql script twice - instead of once and the 
other one once - and it asks you to use them before the webcyradm.deb has 
been installed), I >>think<< I've got it installed correctly now - the tests 
at the end of the real how to all seem to work.

My question is about freeform usernames.
I noticed that Rasjid Wilcox said in an email 2 weeks ago that usernames such 
as "bob", "dave", "grandpa" etc are possible with 0.5.4
Therefore, I've tried to install 0.5.4

the debian how to deals with installing 0.5.3, so I ran the 0.5.3->0.5.4 
upgrade sql scripts

Now I've gone through the real how to again, and I still can't find how to 
enable these freeform usernames on 0.5.4 (but its possible that my upgrade 
has not been complete, and I'm missing something?)
So what do I need to do to use them?

The second question I have is about the debian setup.
I've got everything running - mysqld runs fine, as does postfix, however - 
when I try to log in to web-cyradm, I get a database error.
This is because it can't connect to mysqld, because /var/run/mysqld is deleted 
on startup (its a symlink in the how to).
I can't understand how to get it to work on bootup without having to manually 
(or even automatically...) create this symlink so any help would be 
appreciated

Thanks for any help,

Bob
