I've chatted with Simon on IM.

Well, it is simple enough...  Just a property with a boolean value.  A
Sun engineer has an implementation of this in a wad that's soon to go
into Solaris, using a "private" property name and code assignment.

I can't think of a good property name :(  How about:

    SASL_RFC4752_INTEROP_BUG
    SASL_GSSAPI_INTEROP_BUG
    SASL_GS1_INTEROP_BUG
    SASL_AD_INTEROP_BUG
    (maybe a different suffix than '_BUG'?)
	If true -> sent '6' instead of '4'.

I like the first two best.  The last one is probably the most meaningful
to developers, IMO -- apparently AD uses a different SASL/GSSAPI
implementation than Exchange, so this interop bug may be limited to AD,
though I've no evidence either way.

Thanks!
