WordPress MU

I posted a similar message over on the Wordpress.org forums about this but the problem seems to affect my MU installation and not stand alone blogs. Here is the problem:

I have a plugin that uses NTLM to authenticate the user. This part of the plugin seems to work just fine on stand along blogs. I can't test it in MU because when I activate the plugin, I need to set some options for the plugin. While this plugin is active, I can not save options on any plugin, including this one. The form post always comes back blank. If I disable this plugin it still causes this issue until I close the browser and reopen it. This one has me stumped.

I am using MU 1.5.1 right now as we need to use the WPDirAuth plugin which seems stable only in that version. Besides that, I can disable all other plugins and the problem persists. I have to assume it is something with the NTLM authentication which sends headers if the user is not yet authenticated. Perhaps the post variables are lost there, any thoughts?

Well, I followed the directions at for creating my options page and it looks great, but, when I click the update button I get the darn "Are you sure you want to do this?" error. It's been too long since I have written a plugin - anyone remember how to do it for version 1.5.1? I can make it work great in 2.7!

Sorry, I meant MU 2.5.1, not 1.5.1. No matter what I do, I get that damn error in MU and it is just killing me. Why can't I make this work? Hasn't anyone use the auto save options feature in plugins for MU?

Well, I got it to work using the method described here:
