Hi Vegard,

I'll admit, I'm not as familiar with Kerberos myself. But, DSpace does 
not come with a Keberos authentication plugin. Therefore, DSpace does 
not support Kerberos out-of-the-box. Here's the authentication plugins 
which are provided:

https://wiki.duraspace.org/display/DSDOC5x/Authentication+Plugins

If you are willing to do some Java programming (or have someone onsite), 
it may be possible for you to build a custom Kerberos authentication 
plugin for DSpace (by implementing a new 
"org.dspace.authenticate.AuthenticationMethod"). I'd recommend looking 
at some of the existing Authentication plugins as examples:
https://github.com/DSpace/DSpace/tree/master/dspace-api/src/main/java/org/dspace/authenticate

It's also possible someone else has found a way to use DSpace with 
Kerberos. If so, hopefully they'll speak up and share their code and/or 
experiences in doing so.
