Windows accounts with spaces and ampersands in their names cause problems?

[Richard Sharpe]

Hi folks,

I have a situation where we have a user with an account "xxxyyyy R&d"
and under Samba 3.6.6 when you authenticate with NTLM it works, but
with Kerberos it does not.

We see lots of these messages in the log with Kerberos:

  Kerberos ticket principal name is [LabVIEW\ R&D at NIMBUS-10.SOMEWHERE.COM]
