ad provider - mangle user names

[Frank Ritchie]

Hi all,

Looking to have my cake and eat it too.

I have alot of users that have been using Winbind for years. They currently
log in with the workgroup, ie:

WORKGROUP+username

I would like to roll out SSSD with the ad provider. I would ideally like
for a user to be able to log in as:

WORKGROUP+username

or

username

and sssd would know this is the same AD user.

Is this possible?

thx
