Logout button Implementation as a Web Part
This Web Part Implement a logout button to the top nav bar in WSS or SPS 2003.
I adapted the code to remove the need to modify the original Sharepoint file (OWSBROWS.JS). Just drop the web part anywhere in each pages you want to use the logout button. This way, if you use an external service provider or you do not want to modify the original installation file, you can get your feature anyway.
Edit the source from the web part to modify the wording and/or the colors.
The current version has the wording in French. since there are no dll, you can import it directly to your site.
