We have a proxyOld.c module that we bundle with Connexitor that handles
part of the problem. It dynamically adds a new control handler that
recognizes the obsolete OID and parses its values, then does the usual
slap_sasl_authorized validation. I don't think supporting this obsolete
spec in the mainline code is a good idea.
My problem is different: I don't care about supporting it at control
__decoding__; I need to support it at control __encoding__, when
requesting proxyAuthz inside back-ldap. This wouldn't be mainstream at
all, IMHO.
