How to compare two user accounts, with partial and fully qualified domain name

[ajayindelhi]

Hi,

I have two user accounts in the format:

<domain>\<alias >

and

<fully qualified domain name>\<alias>


In both the cases, <alias> is same. I want to check if both of these accounts are same or not. This is because, sometime user can just enter the first format and some times, the user can enter the domain name in long format.

Any help would be appreciated.

Thanks,
