Learned about Apache module mod_macro today.
I was trying to configure Digest authentication in Apache and I was getting Internal Server Error 500 when trying to access my site. The Apache error log reported: “configuration error: couldn’t check user. No user file?”
Turned out the problem was that I hadn’t installed the Digest auth module. So the fix was:
# a2enmod auth_digest # apache2ctl graceful
Reading about Subversion Path-Based Authorization.
Reading about Digest authentication in Apache for Subversion.
Was just having a look into what kind of support there was for OpenID in the software that I use, and basically it looks like there is fairly good support. Mailman might be a bit of a trick.
