    I'm using the "TelerikADMembershipProvider" Member Provider and, as a result, the "Find Username" in the Administration section doesn't work.

    To get this to work I had to override the "FindUsersByName" method and replace the "%" with "*" in the UserName string.  Here is the code:

    using System;  
    using System.Collections.Generic;  
    using System.Text;  
    using System.Text.RegularExpressions;  
    using System.Web;  
    using System.Web.Security;  
    namespace Security  
        class CustomMemberProvider : Telerik.Security.ActiveDirectory.TelerikADMembershipProvider  
            public override MembershipUserCollection FindUsersByName(string usernameToMatch, int pageIndex, int pageSize, out int totalRecords)  
                string newUsername = Regex.Replace(usernameToMatch, @"\%", "*");  
                return base.FindUsersByName(newUsername, pageIndex, pageSize, out totalRecords);  

    I'm not sure why this is needed.  But the code above seems to work and make the Active Directory username search working.

    Hello Gabe,

    Thanks for the feedback. We are aware of this issue -  it is also valid for the search-by-letter functionality.

    In queries against an Active Directory data source the wildcard ( * ) is equal to the wildcard ( % ) in sql syntax. 

    For example, if you search for "john" with an sql provider your query is similar to: SELECT ... WHERE username LIKE %john% ... and if you use an active directory provider your query should be similar to: ... (sAMAccountName=*john*) ... 

    This bug is already fixed the changes will be available with the service pack.

    Kind regards,
    the Telerik team
