What do the messages below mean?  I lost all network connectivity and 
started receiving these messages after changing username map from root = 
DELSOLW2K\Administrator to root = @"DELSOLW2K\Domain Admins".
The system is Debian Sarge with Simo's latest debs and security = ADS.

Using host libthread_db library "/lib/tls/libthread_db.so.1".
`system-supplied DSO at 0xffffe000' has disappeared; keeping its symbols.
[Thread debugging using libthread_db enabled]
