Does anybody out there use Authentication Header (AH)?

I'm using AH for OSPFv2 and OSPFv3 authentication.  For OSPFv3, there
is no other option than some kind of IPsec for authentication.  I'm
also using it for OSPFv2 so I don't have to maintain multiple
authentication methods and keys for the different protocols.
