Problem logging in because of 'Non-unique path' [SOLVED]

[nickdegraeve]

We had an Alfresco installation (2.1 I guess) running on a Windows server. The harddisk of the machine crashed and now I restored the backups to the latest Alfresco version on a Linux server. I had quite some difficulties getting the DB to upgrade but after some tweaking as suggested here, it seems the DB is upgraded and patches were successfully applied. At the end I got some more errors but they didn't seem to prevent the server from starting:

The real problem is when I try to login at http://localhost:8080/alfresco. I'm forwarded to http://localhost:8080/alfresco/faces/jsp/dashboards/container.jsp and I get following system error:

org.alfresco.error.AlfrescoRuntimeException: Failed to authenticate as Guest user.
caused by:
java.lang.IllegalStateException: Non-unique path: found : /app:company_home/app:user_homes 0‍‍‍

What goes wrong? And how can I resolve it?

Many thanks in advance.

The full stacktrace is

I was able to solve it myself.

I disabled guest login and the problem was gone.

Hi!

We are experiencing the same problem. How did you disable guest login? Thanks!

[nickdegraeve]

I believe it was somewhere in the authentication services config. You just need need  to set "allowGuestLogin" to false.
