2007-10-10r15426: Implement SPNEGO as the default RPC authentication mechanism. WhereAndrew Bartlett1-0/+9
this isn't supported, fallback to NTLM. Also, where we get a failure as 'logon failure', try and do a '3 tries' for the password, like we already do for CIFS. (Incomplete: needs a mapping between RPC errors and the logon failure NTSTATUS). Because we don't yet support Kerberos sign/seal to win2k3 SP1 for DCE/RPC, disable this (causing SPNEGO to negotiate NTLM) when kerberos isn't demanded.

2007-10-10r13481: As far as I can tell, my changes in -r 12863 were dangerously untested.Andrew Bartlett1-7/+8
We do need the gsskrb5_get_initiator_subkey() routine. But we should ensure that we do always get a valid key, to prevent any segfaults. Without this code, we get a different session key compared with Win2k3, and so kerberised smb signing fails. Andrew Bartlett (This used to be commit cfd0df16b74b0432670b33c7bf26316b741b1bde)

responses... Also trust OpenLDAP to be pedantic about it, breaking connections to AD. In any case, we now get this 'right' (by nasty overloading hacks, but hey), and we can now use system-supplied OpenLDAP libs and SASL/GSSAPI to talk to Samba4. Andrew Bartlett (This used to be commit 0cbe18211a95f811b51865bc0e8729e9a302ad25)
2007-10-10r13342: Make the GSSAPI SASL mech actually work, by (shock horror) reading ↵Andrew Bartlett1-70/+406
the spec. GSSAPI differs from GSS-SPNEGO in an additional 3 packets, negotiating a buffer size and what integrity protection/privacy should be used. I worked off draft-ietf-sasl-gssapi-03, and this works against Win2k3. I'm doing this in the hope that Apple clients as well as SASL-based LDAP tools may get a bit further. I still can't get ldapsearch to work, it fails with the ever-helpful 'Local error'. Andrew Bartlett (This used to be commit 3e462897754b30306c1983af2d137329dd937ad6)

2007-10-10r13206: This patch finally re-adds a -k option that works reasonably.Andrew Bartlett1-2/+3
From here we can add tests to Samba for kerberos, forcing it on and off. In the process, I also remove the dependency of credentials on GENSEC. This also picks up on the idea of bringing 'set_boolean' into general code from jpeach's cifsdd patch. Andrew Bartlett (This used to be commit 1ac7976ea6e3ad6184c911de5df624c44e7c5228)
2007-10-10r12863: As lha suggested to me a while back, it appears that theAndrew Bartlett1-8/+7
gsskrb5_get_initiator_subkey() routine is bougs. We can indeed use gss_krb5_get_subkey(). This is fortunate, as there was a segfault bug in 'initiator' version. Andrew Bartlett (This used to be commit ec11870ca1f9231dd3eeae792fc3268b31477e11)

(This used to be commit 70e7449318aa0e9d2639c76730a7d1683b2f4981)
2007-10-10r11995: A big kerberos-related update.Andrew Bartlett1-54/+7
This merges Samba4 up to current lorikeet-heimdal, which includes a replacement for some Samba-specific hacks. In particular, the credentials system now supplies GSS client and server credentials. These are imported into GSS with gss_krb5_import_creds(). Unfortunetly this can't take an MEMORY keytab, so we now create a FILE based keytab as provision and join time. Because the keytab is now created in advance, we don't spend .4s at negprot doing sha1 s2k calls. Also, because the keytab is read in real time, any change in the server key will be correctly picked up by the the krb5 code. To mark entries in the secrets which should be exported to a keytab, there is a new kerberosSecret objectClass. The new routine cli_credentials_update_all_keytabs() searches for these, and updates the keytabs. This is called in the provision.js via the ejs wrapper credentials_update_all_keytabs(). We can now (in theory) use a system-provided /etc/krb5.keytab, if krb5Keytab: FILE:/etc/krb5.keytab is added to the secrets.ldb record. By default the attribute privateKeytab: secrets.keytab is set, pointing to allow the whole private directory to be moved without breaking the internal links. (This used to be commit 6b75573df49c6210e1b9d71e108a9490976bd41d)

2007-10-10r11543: A major upgrade to our KDC and PAC handling.Andrew Bartlett1-1/+1
We now put the PAC in the AS-REP, so that the client has it in the TGT. We then validate it (and re-sign it) on a TGS-REQ, ie when the client wants a ticket. This should also allow us to interop with windows KDCs. If we get an invalid PAC at the TGS stage, we just drop it. I'm slowly trying to move the application logic out of hdb-ldb.c, and back in with the rest of Samba's auth system, for consistancy. This continues that trend. Andrew Bartlett (This used to be commit 36973b1eef7db5983cce76ba241e54d5f925c69c)
2007-10-10r11521: Add in client support for checking supportedSASLmechanisms, and thenAndrew Bartlett1-0/+1
determining a mechanism to use. Currently it doesn't to fallbacks like SPNEGO does, but this could be added (to GENSEC, not to here). This also adds a new function to GENSEC, which returns a list of SASL names in our preference order (currently determined by the build system of all things...). Also make the similar function used for OIDs in SPNEGO do the same. This is all a very long-winded way of moving from a hard-coded NTLM to GSS-SPNEGO in our SASL client...

2007-10-10r11468: Merge a bit more of init_sec_context from Heimdal CVS into ourAndrew Bartlett1-1/+8
DCE_STYLE modified version, and add parametric options to control delegation. It turns out the only remaining issue is sending delegated credentials to a windows server, probably due to the bug lha mentions in his blog (using the wrong key). If I turn delgation on in smbclient, but off in smbd, I can proxy a cifs session. I can't wait till Heimdal 0.8, so I'll see if I can figure out the fix myself :-) Andrew Bartlett (This used to be commit fd5fd03570c13f5644e53ff89ac8eca7c0985740)

2007-10-10r11270: Move the core CrackNames code from rpc_server/drsuapi to dsdb/samdb.Andrew Bartlett1-35/+6
I'm sure this will not be the final resting place, but it will do for now. Use the cracknames code in auth/ for creating a server_info given a principal name only (should avoid assumtions about spliting a user@realm principal).

authentication. This pulls the creating of the keytab back to the credentials code, and removes the special case of 'use keberos keytab = yes' for now. This allows (and requires) the callers to specify the credentials for the server credentails to GENSEC. This allows kpasswdd (soon to be added) to use a different set of kerberos credentials. The 'use kerberos keytab' code will be moved into the credentials layer, as the layers below now expect a keytab. We also now allow for the old secret to be stored into the credentials, allowing service password changes. Andrew Bartlett (This used to be commit 205f77c579ac8680c85f713a76de5767189c627b)

2007-10-10r10291: The patch optionally (off by default, not available in all cases) allowsAndrew Bartlett1-5/+15
Samba to use the target principal name supplied in the mechTokenMIC of an SPNEGO negTokenInit. This isn't a great idea for security reasons, but is how Samba3 behaves, and allows kerberos to function more often in some environments. It is only available for CIFS session setups, due to the ordering of the exchange. Andrew Bartlett (This used to be commit f6a645644127ae695a9f7288e0a469f2eb7f3066)
2007-10-10r10153: This patch adds a new parameter to gensec_sig_size(), the size of theAndrew Bartlett1-9/+46
data to be signed/sealed. We can use this to split the data from the signature portion of the resultant wrapped packet. This required merging the gsskrb5_wrap_size patch from lorikeet-heimdal, and fixes AES encrption issues on DCE/RPC (we no longer use a static 45 byte value). This fixes one of the krb5 issues in my list. Andrew Bartlett (This used to be commit e4f2afc34362953f56a026b66ae1aea81e9db104)
2007-10-10r10066: This is the second in my patches to work on Samba4's kerberos support,Andrew Bartlett1-37/+77
with an aim to make the code simpiler and more correct. Gone is the old (since the very early Samba 3.0 krb5 days) 'iterate over all keytypes)' code in gensec_krb5, we now follow the approach used in gensec_gssapi, and use a keytab. I have also done a lot of work in the GSSAPI code, to try and reduce the diff between us and upstream heimdal. It was becoming hard to track patches in this code, and I also want this patch (the DCE_STYLE support) to be in a 'manageable' state for when lha considers it for merging. (metze assures me it still has memory leak problems, but I've started to address some of that). This patch also includes a simple update of other code to current heimdal, as well as changes we need for better PAC verification. On the PAC side of things we now match windows member servers by checking the name and authtime on an incoming PAC. Not generating these right was the cause of the PAC pain, and so now both the main code and torture test validate this behaviour. One thing doesn't work with this patch: - the sealing of RPC pipes with kerberos, Samba -> Samba seems broken. I'm pretty sure this is related to AES, and the need to break apart the gss_wrap interface. Andrew Bartlett (This used to be commit a3aba57c00a9c5318f4706db55d03f64e8bea60c)
2007-10-10r10035: This patch removes the need for the special case hackAndrew Bartlett1-2/+19
'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.

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.
