SimpleSAMLphp with WordPress on OpenShift

These are the steps that I used to get SimpleSAMLphp running with WordPress on OpenShift.

First, copy the files up to the server and decompress them.

$ rhc scp MYAPP upload simplesamlphp.tar.gz app-root/data
$ rhc ssh MYAPP
$ cd app-root/data
$ tar -zxf simplesamlphp.tar.gz


Then, link it to a public WordPress directory e.g. uploads

$ cd uploads
$ ln -s ../simplesamlphp/www/ saml
$ cd ../simplesamlphp


Then, just configure SimpleSAMLphp as usual.

The only key thing to note is that the baseurlpath needs to be configured with a FULL path name. For some reason, SimpleSAMLphp was unable to detect that it was running behind a reverse proxy.
