[squid-users] ntlmGetString: insane: ?

Hi,
 
Some of our users with IE7 gets prompted for auth credentials all the time.
And when debugging fakeauth_auth I get ntmlGetString: insane: l:32 o:88

fakeauth_auth[7382](fakeauth_auth.c:399): Got 'KK
TlRMTVNTUAADAAAAGAAYAIIAAAAYABgAmgAAAAYABgBIAAAAIgAiAE4AAAASABIAcAAAAAAAAACy

fakeauth_auth[7382](fakeauth_auth.c:283): ntlmDecodeAuth: size of 256
fakeauth_auth[7382](fakeauth_auth.c:284): ntlmDecodeAuth: flg 02008205
fakeauth_auth[7382](fakeauth_auth.c:285): ntlmDecodeAuth: usr o(78) l(34)
fakeauth_auth[7382](fakeauth_auth.c:289): ntlmDecodeAuth: Domain 'EDU'.
fakeauth_auth[7382](fakeauth_auth.c:293): ntlmDecodeAuth: Domain 'EDU'.
ntlmGetString: insane: l:34 o:78
fakeauth_auth[7382](fakeauth_auth.c:425): sending 'NA invalid credentials,
user=edu\' to squid

and another:
 
fakeauth_auth[7382](fakeauth_auth.c:399): Got 'KK

ntlmGetString: insane: l:32 o:88
fakeauth_auth[7382](fakeauth_auth.c:425): sending 'NA invalid credentials,
user=adm\' to squid

And most of them seems to work directly.
Any ideas?
