ADFS authentication - IE8 works, Chrome fails

Question

so, have web-site configured for ADFS 2.0 authentication...

for IE - it works fine and did authentication correct

for Chrome - it reaches redirect to AD FS server... ask to authenticate but could not authenticate.

I try to requests using fiddler but it show nothing interesting - so show that we redirect to adfs for authentication but nothing more

what it could be? why it is impossible to authenticate for chrome

thanks
