I have box for a while and asked SM to install CPanel on it.

After installation I realized that newly created accounts have wrong GroupID:UserID.
They can be found in the /etc/passwd, /etc/group

On my other box Cpanel accounts started from 32000 ID.
But on this box they started just right from 500.

Also when new account created I have record in /etc/passwd with GroupID and UserID+1, i.e. for accounts ac1, ac2, ac3 I have records:

That way I have all quota on my box mixed between different acounts and experienced much problems.

So my question - how to make Cpanel start creating account from 32000 ?

I tried manually update last records from /etc/passwd, /etc/group but it seems Cpanel does not take data from these files for creating new accounts.

Please help me!..

I beleive there is an option in WHM to set the minimum UID

Look for Minimum Uid: under setup

strange, I did not recieve post notification

yes, it helps, thank you!..
