Fat client fails to authenticate

[Valerio Pachera]

Hi, I just run ltsp-buil-client and I'm testing a fat client.
The fat client boots without problem but I can't log in.
This is what I get from syslog:

As suggested in the guide I enabled ndb compression removing
NO_COMP="-noF -noD -noI -no-exports"
before running ltsp-build-client.

What is wrong?
Which other information may I report?

Thank you.
