Is it possible to have one login instead of multiple?

I currently have DirectAdmin servers and ClientExec installed on one of them. I want it so that the customer can login once and then be able to go back and forth without having to log into each system. I've heard this can be done with LDAP, but I have no clue how to set that up. Any suggestions?

LDAP can support many types of applications for ex. like Joomla & PHPBB and is very general which includes basic security. But not really sure about Directadmin application if it will support LDAP.

Well, this is the biggest problem when you are using a control panel that doesn't include billing...

You could get a system that supports (ties into) your control panel, or create your own method, if you know how to code. It shouldn't be too difficult to do if you can code. If not, you should be able to hire someone to do it. There are a few ways to accomplish such a task.

You seem to be wanting to combine un-combined things all in one.
I understand your wishes to merge DirectAdmin and ClientExec just to have better and flexible billing & admin control panel performance. But those are two quite separate software with quite separate purposes. I am afraid there's nothing you can do unless source code modification like it was suggested.
Besides, having only one login is dangerous in the light of system security.

There's one thing you can do: use a control panel that does have billing integrated, so you don't need yet-another software...
