how to remove membership provider name from the User Name in FBA web application

Hi all,

I’ve setup a FBA web appln. usesr have added into the  sql db , [ by applying aspnet_regsql] command and   created  aspnetdb  in the   sql server.

The only problem I am having is with the adminuser login display name. when the admin user logged in, its shows the  FBA membership provider's name also . like  "i:0#.f|mymembershipprovider|dmsadmin”.

How do I get rid of the membership provider name on this top right hand corner?

so that, the admin user login display name will only show “dmsadmin”.

when other end users  were logged-in to the appln , they    are not facing this issue. the issue happens ONLY for the Admin User.

any help is appreciated , on how to resolve this issue.
