What TMOS version are you running?

 

11.1.0 - 11.3.0 has a bug sol13821: HTTP monitors may fail when NTLM authentication is required

 

I also agree with Jinshu's approach of using an external monitor and personally I use for almost all HTTP/HTTPS monitors that need NTML authentication.

 

The only thing I would say is watch your backend servers as you could end up with a lot of open authenticated sessions on the servers. If this is an issue write an external monitor that closes the authenticated session after performing its checks.
