Surprised that no one is willing to answer my query. If I had to get any help from my service provider, would I have asked this question here ???
But you
did ask him first:
...... My service provider tell me use the sub account password that I have set but that does not work. Why will he give me the server root password. I do not want to login to the cpanel I want to login to WHM.
cPanel for the customer is not the same as WHM for the server administrator.
So, when you ask:
.....I want to login into any of my sub accounts directly that I have created in WHM (I have 4 sub accounts in WHM) using
http://subaccount1.com/whm. Is this possible then how.
The answer is No. Not unless all 4 of your
sub accounts are resellers (and have access to WHM)
I think you may be naming things incorrectly and therein is the confusion.
Let's assume you have a reseller account, and you've created 4 new hosting accounts under your reseller account.
yourdomain.com <- the reseller
-hisdomain.com
-herdomain.com
-mydomain.com
-itsdomain.com
As the reseller (and, if the option is enabled in WHM by your provider) these should work.
yourdomain.com
/whm <- the reseller
-hisdomain.com
/cpanel
-herdomain.com
/cpanel
-mydomain.com
/cpanel
-itsdomain.com
/cpanel
Because you are a reseller, your provider is the one you ask for assistance from. If they can't assist, spend your money elsewhere and find a new reseller provider.
