Virtual server can't authenticate user with active directory through NTLM service.

Step 1: User clicks on a button running VS37. VS 37 has HTTP enabled and running NTLM service. NTLM service authenticate user through Active directory with IP 192.168.29.0/24. After authentication VS37 has to redirect towards VS38.

Step 2: VS38 is webserver. The point here is once VS37 is performing authentication with Active Directory, session affinity has to be maintained b/w VS37 and VS38.

Note : For redirection i have also created below mentioned iRule. when HTTP_REQUEST { virtual VS38 }

I have applied this iRule on VS37 but it didn't worked.

Looking forward for solution.
