ITS#5369 SASL/GSSAPi refactoring from Stefan Metzmachermetze@samba.org and Rafal Szczeniakmimir@samba.org, with minor cleanups
This is buggy:
Feel free to patch whatever makes sense. I don't have any SMB servers running at the moment to test against. There were certainly a lot of flaws in the code; my main motivation for committing it was that it helped to compartmentalize the Cyrus-specific code. Since I doubt that anything besides Samba4 will ever use the gssapi.c portion, it's not a big concern at the moment. If it's broken, I expect the Samba guys to let us know.
pkt_len is used uninitialized in sb_sasl_gssapi_decode().
guess_service_principal() is broken: It uses 'ret' uninitialized, as if a return value from malloc. It passes (buffer length - 1) instead of buffer length to snprintf, which I think fails for the (allow_remote&& givenstr) case. snprintf() unnecessary anyway since the function can malloc the exact needed size. Also it's preferable to only use a string literal as format argument, so gcc can verify the printf (instead of warning that it can't).
Format errors: OM_uint32 printed as %u, size_t/ber_len_t as %lu.
Here is a draft patch. Untested. Note I've not looked at how this actually works, just how to get rid of warnings. http://folk.uio.no/hbf/OpenLDAP/gssapi.txt
Finally, some header files should declare these functions: ldap_gssapi_bind_s(), ldap_int_gssapi_close(), ldap_int_gssapi_config(), ldap_int_gssapi_get_option(), ldap_int_gssapi_set_option(), ldap_pvt_sasl_generic_install(), ldap_pvt_sasl_generic_remove(), and be #included by bind.c, cyrus.c, gssapi.c, init.c, options.c, request.c.
