I had posted this message on the forum:

http://www.dotnetnuke.com/Community/ForumsDotNetNuke/tabid/795/forumid/89/threadid/20097/scope/posts/Default.aspx

Oddly, I haven't done a thing about this until today when I decided to try and work on it again.  However, it worked.  I haven't changed a thing, and now its working, as long as I provide a legitimate user id and password.  Hmm, makes me nervous about moving forward with rolling this out on the intranet.

But, I am getting an error message if the authentication fails.  If I enter a legitimate user id with the wrong password, or an invalid user id with a password, I get the following error message:

A critical error has occurred.
StartIndex cannot be less than zero. Parameter name: startIndex


Interestingly, this is the same error message I was getting that I referenced in the post above.  However, in my post above, the error caused an ASP.NET level exception and I got the stack dump along with the error message.  This time, something is apparently catching the exception and displaying it on the page.  In the post above, I saw no sign of DNN, just an error page with the excetpion and stack dump.  In this scenario, I get the DNN skin with page rendered just fine, but with the error message displayed in one of the panes.

Can anyone help me resolve this?  I can't roll this out if the user gets an exception when they enter their password wrong.

Thanks.

Oops!!!  Ok, scratch this whole post.  It turns out that I didn't have AD turned on in the web.config file today.  Now that I turned it back on, I am back to the error that mysteriously disappeared.  Actually, I am glad that is the case, but now if I can get that original problem solved I reported in the post at the link I referenced above.

Thanks.

Ok, if you see this message, go here to read the solution:

http://www.dotnetnuke.com/Community/ForumsDotNetNuke/tabid/795/forumid/89/threadid/20097/scope/posts/Default.aspx

It turns out my admin user's email address was wrong and did not contain at @ sign.

This problem manifests itself one way if AD is turned on and a different way if AD is turned off.

I had the same error ' StartIndex cannot be less than zero. Parameter name: startIndex' but mine was not to do with user email address or any other authentication.

I traced the error to the 'EdtiSkins.ascx.vb' file, on line 292 (4.5.1 release), where it was doing the following:

strURL = strFile.Substring(strFile.LastIndexOf(

"\portals\"))

I then looked at where my portal subdirectory had been created (I overwrite the default portals\1 setting for a child portal) and it had created it at the website root level, so dotnetnuke\myPortal rather than dotnetnuke\portals\myPortal.  The hardcoded search for the 'portals' subdirectory call above then failed.  I manually updated the portals record with the correct subdirectory, restarted my website and it worked OK.  A trap for young players trying to override the default portals folder location.
