This field, if defined, should consist of a VARCHAR consisting of a
comma-separate list of "IDENTIFIER=VALUE" pairs, that specify per-account

What is the =VALUE meant to be for these AUXOPTIONS... 1/0, Y/N, Yes/No ?
See INSTALL's description of the "Account OPTIONS" setting for more

The main install file then says...
See ACCOUNT OPTIONS in the auth_generic manual page.
but I couldn't find anything seemingly related here...
