thanks a lot. will test that in a few hours and report back.
INVALID_WORKSTATION is really causing me big headaches at the moment.
yesterday i checked HEADs smbd that suffers *not* from this problem.  but
obviously winbindd (either 2_2 or HEAD/3_0) receives the same
error-message from the domain controller on several occasions. this is
currently rendering my squid-ntlm-winbind-proxy unusable... and should be
fixed IMHO. should I file a bugzilla-entry? 

btw: did you know that ADS refuses to accept simple ldap binds from hosts
not in "userworkstations" ? sasl-gssapi-binds does work from these hosts

thanks again,
