2007-10-10r10035: This patch removes the need for the special case hackAndrew Bartlett3-34/+65
'MEMORY_WILDCARD' keytab type. (part of this checking is in effect a merge from lorikeet-heimdal, where I removed this) This is achieved by correctly using the GSSAPI gsskrb5_acquire_cred() function, as this allows us to specify the target principal, regardless of which alias the client may use. This patch also tries to simplify some principal handling and fixes some error cases. Posted to samba-technical, reviewed by metze, and looked over by lha on IRC.

StrCaseCmp was sys_strcasecmp, while it is in fact strcasecmp_m! (This used to be commit 200a8f6652cb2de7a8037a7a4c2a204b50aee2b1)
2007-10-10r9728: A *major* update to the credentials system, to incorporate theAndrew Bartlett2-50/+18
Kerberos CCACHE into the system. This again allows the use of the system ccache when no username is specified, and brings more code in common between gensec_krb5 and gensec_gssapi. It also has a side-effect that may (or may not) be expected: If there is a ccache, even if it is not used (perhaps the remote server didn't want kerberos), it will change the default username.

2007-10-10r9648: this fixes the krb5 based login with the pac. The key to this whole ↵Andrew Tridgell2-1/+8
saga was that the logon_time field in the pac must match the authtime field in the ticket we gave the client in the AS-REP (and thus also the authtime field in the ticket we get back in the TGS-REQ). Many thanks to Andrew Bartlett for his patience in showing me the basic ropes of all this code! This was a joint effort. (This used to be commit 7bee374b3ffcdb0424a83f909fe5ad504ea3882e)

caused me pain (and covourty warnings). Simply gensec_gssapi to assume the properties of lorikeet-heimdal, rather than having #ifdef around critical features. This simplifies the code rather a lot. Andrew Bartlett (This used to be commit 11156f556db678c3d325fe5ced5e41a76ed6a3f1)

2007-10-10r9084: 'resign' the sample PAC for the validation of the signature algorithms.Andrew Bartlett2-91/+190
If we ever get problems with the kerberos code, it should show up as a different signature in this PAC. This involved returning more data from the pac functions, so changed some callers and split up some functions. Andrew Bartlett (This used to be commit d514a7491208afa0533bf9e99601147eb69e08c9)

2007-10-10r8252: Steal metze's thunder, and prove that with a few small tweaks, we canAndrew Bartlett1-2/+2
now push/pull a sample PAC, and still have the same byte buffer. (Metze set up the string code, and probably already has a similar patch). Unfortunetly win2k3 still doesn't like what we provide, but every step helps. Also use data_blob_const() when we are just wrapping data for API reasons. Andrew Bartlett (This used to be commit e7c8076fc1459ff2ccefdaf0b091d04ee6137957)
2007-10-10r8250: More PAC work. We now sucessfully verify the KDC signature from my DCAndrew Bartlett2-22/+34
(I have included the krbtgt key from my test network). It turns out the krbtgt signature is over the 16 (or whatever, enc-type dependent) bytes of the signature, not the entire structure. Also do not even try to use Kerberos or GSSAPI on an IP address, it will only fail. Andrew Bartlett (This used to be commit 3b9558e82fdebb58f240d43f6a594d676eb04daf)

2007-10-10r8110: More PAC work. I still can't get WinXP to accept the PAC, but we areAndrew Bartlett2-39/+73
much closer. This changes PIDL to allow a subcontext to have a pad8 flag, saying to pad behind to an 8 byte boundary. This is the only way I can explain the 4 trainling zeros in the signature struct. Far more importantly, the PAC code is now under self-test, both in creating/parsing our own PAC, but also a PAC from my win2k3 server. This required changing auth_anonymous, because I wanted to reuse the anonymous 'server_info' generation code. I'm still having trouble with PIDL, particulary as surrounds value(), but I'll follow up on the list. Andrew Bartlett (This used to be commit 50a54bf4e9bf04d2a8e0aebb3482a2ff655c8bbb)

2007-10-10r7993: Further work on the Krb5 PAC.Andrew Bartlett4-23/+184
We now generate the PAC, and can verifiy both our own PAC and the PAC from Win2k3. This commit adds the PAC generation code, spits out the code to get the information we need from the NETLOGON server back into a auth/ helper function, and adds a number of glue functions. In the process of building the PAC generation code, some hints in the Microsoft PAC specification shed light on other parts of the code, and the updates to samr.idl and netlogon.idl come from those hints. Also in this commit: The Heimdal build package has been split up, so as to only link the KDC with smbd, not the client utils. To enable the PAC to be veified with gensec_krb5 (which isn't quite dead yet), the keyblock has been passed back to the calling layer.

2007-10-10r7978: A start again on PAC verification. I have noticed that the kerberosAndrew Bartlett2-50/+35

2007-10-10r7827: Add in-memory keytab to Samba4, using the new MEMORY_WILDCARD keytabAndrew Bartlett5-107/+213
support in Heimdal. This removes the 'ext_keytab' step from my Samba4/WinXP client howto. In doing this work, I realised that the replay cache in Heimdal is currently a no-op, so I have removed the calls to it, and therefore the mutex calls from passdb/secrets.c. This patch also includes a replacement 'magic' mechanism detection, that does not issue extra error messages from deep inside the GSSAPI code.

2007-10-10r7352: the internal heimdal build change. This changes quite a few things:Andrew Tridgell1-0/+2
- if you want kerberos now, you need to unpack a lorikeet heimdal tree in source/heimdal/. If source/heimdal/ does not exist at configure time then all kerberos features are disabled. You cannot use an external kerberos library for now. That may change later. - moved lib/replace/ config stuff to lib/replace/ and create a lib/replace/replace.h. That allows the heimdal build to use our portability layer, and prevenets duplicate definitions of functions like strlcat() - if you do enable heimdal, then you will need to do 'make HEIMDAL_EXTERNAL' before you build Samba. That should be fixed once I explain the problem to jelmer (the problem is the inability to set a depend without also dragging in the object list of the dependency. We need this for building the heimdal asn1 compiler and et compiler. - disabled all of the m4 checks for external kerberos libraries. I left them in place in auth/kerberos/, but disabled it in configure.in some of the heimdal_build/ code is still very rough, for example I don't correctly detect the correct awk, flex, bison replacements for heimdal_build/build_external.sh. I expect to fix that stuff up over the next few days. (This used to be commit d4648249b2c7fc8b5e7c0fc8d8f92ae043b5691f)

fill in the function pointers to handle the logging, and catch all the kerberos warnings. (Currently at level 3). To avoid a memory leak, this requries a new function: krb5_freelog(), which I've added to lorikeet/heimdal. This also required a revamp to how we handle the krb5_context, so as to make it easier to handle with talloc destructors.

2007-10-10r6800: A big GENSEC update:Andrew Bartlett4-4/+131
Finally remove the distinction between 'krb5' and 'ms_krb5'. We now don't do kerberos stuff twice on failure. The solution to this is slightly more general than perhaps was really required (as this is a special case), but it works, and I'm happy with the cleanup I achived in the process. All modules have been updated to supply a NULL-terminated list of OIDs. In that process, SPNEGO code has been generalised, as I realised that two of the functions should have been identical in behaviour. Over in the actual modules, I have worked to remove the 'kinit' code from gensec_krb5, and placed it in kerberos/kerberos_util.c. The GSSAPI module has been extended to use this, so no longer requires a manual kinit at the command line. It will soon loose the requirement for a on-disk keytab too. The general kerberos code has also been updated to move from error_message() to our routine which gets the Heimdal error string (which may be much more useful) when available.
