A new NTLM Proxy Mode option has been added that changes the behavior of NTLM to utilize the Real Server as a proxy for NTLM authentication validation, improving the security of the overall deployment.
After upgrade to this release, turn on NTLM Proxy Mode by doing the following:
- In the main menu, go to System Configuration > Miscellaneous Options > L7 Configuration.
- Enable the NTLM Proxy Mode check box. This changes the NTLM selection for Client Authentication Mode in all Virtual Services to NTLM-Proxy.
NTLM Proxy Mode is enabled by default for all new deployments of LMOS 7.2.53.0 (and above), as well as the LTS release branch (7.2.48.4 and above).
