Domain "prefix" Issue

Hey,

I noticed this a while back, however I never connected the dots until today.

THE ENVIRONMENT:

I use a "user" naming schema of:

ABC1234

Each domain added to the system is given a unique username, and sub-domains share this username when created. Each domain is and sub-domain also are granted a single "database" (unless one is manually added afterwards)

The default database name schema is like this:

ABC1234 => top-level server (ex. mydomain.com)
ABC1234_mysub => sub-server (ex. mysub.mydomain.com)

THE ISSUE:

If I create two or more domains which use the "same" sub-domain, the first creates the database correctly using my schema above, while all additional domains end up getting different naming schema set by the system.

Ex.
ABC1000 => mydomain01.com
ABC1000_mysub => mysub.mydomain01.com

ABC2000 => mydomain02.com
ABC2000_mysub_mydomain02 => mysub.mydomain02.com

The problem with this is, all domain beyond the first one added to the system using the same "sub-domain" portion, end up breaking my preferred naming schema. Now I can go into the config, and manually change this, or even drop the database and create it manually using the Webmin tool, however this is not desired as this adds more time onto the process of creating new sub-domains, and requires me to remember to do so every time I create a sub-domain which matches another sub-domain.

What I'd prefer is to have the schema work out like this:

ABC1000 => mydomain01.com
ABC1000_mysub => mysub.mydomain01.com

and

ABC2000 => mydomain02.com
ABC2000_mysub => mysub.mydomain02.com

Frankly, I'm not sure if my situation is caused by a bug in the system, or perhaps somewhere the system is finding a conflict that I'm not aware of.

It's also worth noting, that in the above examples, both "mydomain01.com" and "mysub.mydomain01.com" are using the common username of "ABC1000", (the same is true for "mydomain02.com" and "mysub.mydomain02.com" which uses "ABC2000" respectively)

Thanks in advance!
