About ICAT: authn.simple

This is the SIMPLE Authentication plugin for ICAT. It uses no external backend to store the credentials or to verify them. Instead the credentials are statically configured in the properties file. This is mostly useful if you need a separate plugin for one single or at most a very few special accounts. A common use case might be that you authenticate all your users against some external source, such as LDAP, but this source does not provide an entry for your ICAT root account. In this situation you might want to use authn_simple to add the root account to your ICAT.
