ASP.NET ActiveDirectoryMembershipProvider UserName max length
===

I am using the ASP.NET Membership Provider against Active Directory. The username is mapped to the sAMAccountName attribute, and according <a href="http://msdn.microsoft.com/en-us/library/system.web.security.activedirectorymembershipprovider.createuser.aspx">this MSDN article </a> "the common restriction is 20 characters or less".

It appears to be enforced by default because I cannot create users with a username length > 20. How can this be adjusted?

Thanks!
