NTLM profile

hello people,

In F5 guide https://www.f5.com/pdf/deployment-guides/microsoft-exchange-iapp-dg.pdf i saw that in the iRule for combined http traffic is the following rule for HTTP_RESPONSE:

when HTTP_RESPONSE { if { ( [HTTP::header exists "WWW-Authenticate"] && [string tolower [HTTP::header values "WWW-Authenticate"]] contains "negotiate" ) || ( [HTTP::header exists "Persistent-Auth"] && [string tolower [HTTP::header "Persistent-Auth"]] contains "true" ) } { ONECONNECT::reuse disable ONECONNECT::detach disable NTLM::disable } if {[HTTP::header exists "Transfer-Encoding"]} { HTTP::payload rechunk } }

NTLM is necessary if APM is not used ? rest of the iRule will work without NTLM profile attached to the VIP ?

F5 software version is 12.1.1 HF 1 - Service MSX2010

Thanks
