I’ve gotten these warnings on several boxes I’ve been working on in the past of couple weeks. I’m posting the fix I found online as a note.

$ gem list | grep 'rake'
rake (0.9.2.2 ruby)

Answer ‘Y’ to both questions.

Obviously I’m using rvm and not sure if it’s something with the system and rvm that’s causing that.

I got a wo ticket for one of my apps that information on a site wasn’t showing up every time the user logged into the application.

I built the app in .net 4.0 using the Account login template bound to AD. The template authenticates the user and allows them to view certain parts of the site.
Completely puzzled I vnc’d to the users machine to watch them login. Funny enough the user was entering an extra space at the very end of their username.
The Account template and AD binding ignore this space and authenticate the user and redirect them to the default page. On the default page I use their AD username to query their AD account and security groups setup for this particular app. Of course the AD username with a space doesn’t exist and the group list is returned null.

The interesting part of this issue was creating a workaround to strip any unwanted trailing characters in a username.
Since this is a template bound to ActiveDirectoryMembershipProvider I pretty much had only one option, Client Side Javascript.
I included my code for future use. It never ceases to amaze me what users find on accident.
