Rancher authentication with microsoft AD + OTP

Dear experts,

I want to know if rancher supports external authentiation with microsoft AD plus OTP.

My client wants to adop rancher for their cluster management solution. and one of their key requirements is to integrate auth with their current Active Directory + OTP based central authentiation system.

I’ve checked rancher document that support active directory integration but not sure it’s still okay with OTP added.

Any comments and information will be highly appreciated !!!
