If we want to keep the API untact, we can use another function to set
fallback_after_kerberos. The question here is that I don't know if any
applications have used smbc_set_credentials(), it there is no, we can
safely change it. But if there is, we might have to use another function
to set fallback_after_kerberos. :-) But this have to be called in order,
smbc_set_credentials() first, and then set fallback_after_kerberos to
avoid surprise.

It cannot be merged into SMBC_server alone, if this is what you mean.
Because some SMBC_XXX_ctx function don't call SMBC_server() before call
cli_resolve_path(). Maybe it is possible to merge it in
SMBC_parse_path() and SMBC_server().

I am using Linux too. It is linking error, some functions that is used
by libsmbclient are not found.(I cannot remember them exactly, one looks
like related to dictionary parse, and one looks like something in zlib,
several others...). I added "-lrt -liniparser -lnsl  -lz -lcap
-lcom_err" to LDFLAGS to make it work.
