I am in to reseller hosting and currently hosted with 3 diff companies, on cPanel and H-Sphere. At present We are finidng difficulties in responding clients's query about webmail and cpanel paths, everytime they calls we need to ask about "which server you are and which platform?"
I am looking something similar to nettigritty.com > login
So, you want to provide a single logon page for all of your customers, regardless of target platform? The nettiritty.com login page isn't doing a whole lot for me, as a matter of fact, I've spent the last 10 minutes trying to figure out what exactly I'm looking at. It's rather confusing.
It's a tricky problem when you don't control all of the authentication data.
I'd take a different approach. How's this?
1. Create a "portal" page for your customers.
2. Direct portal.theirdomain.com to that site. If that's not possible, try portal.yourdomain.com/theirdomain.com. As long as it's something uniform that you can use as a selector. I'm trying to avoid suggesting a login, as your customers will have another username/password combination they'll need to remember.
3. In a database, keep track of what hosting platform your customers are on, as well as the full URL to those services.
4. Create "login to my control panel", and "login to my webmail" links on your portal page, which really open new windows and direct customers to the third party site. You have a choice. Make them log in again, or keep their login information in a database. The downside, here, is if they change their remote password, your stuff breaks.
There are other benefits to doing it this way, too. Your portal can easily have marketing information, targeted links, and common technical support information on it.
They percieve it as an upgrade, your life gets easier.
