Something I've been meaning to get round to for quite a while is setting up an openID server. I've finally done it! Even better, this server is linked into my ldap server which allows for consistent passwords for everything. Getting it working took quite a while. The openid-ldap software was fairly tricky to configure and the apache configuration was a nightmare for me of regular expressions, something that in all my geek years I've managed to stay away from in any depth. (I've learnt a fair bit through osmosis, but never sat down and looked at some regexp documentation). Read on for my instructions on setting this up.
