Line 84 is explicitly this:

            If System.Web.Security.Membership.ValidateUser(loginName, password) Then

inside this function: Public Overrides Function ValidateUser(ByVal loginName As String, ByVal password As String) As Boolean

 

Do you think it's in this function: Function GetUserInfo

and I change nickName = user.Username to nickName = user.DisplayName?

 

Other functions in this class where this change might make sense:

      Function GetLogonIdentity

      Function FindUserLoginName

 

Thanks for your help.
