2012-01-12heimdal: remove checking of KDC PAC signature, delegate to wdc pluginAndrew Bartlett1-12/+2
The checking of the KDC signature is more complex than it looks, it may be of a different enc type to that which the ticket is encrypted with, and may even be prefixed with the RODC number. This is better handled in the plugin which can easily look up the DB for the correct key to verify this with, and can also quickly determine if this is an interdomain trust, which we cannot verify the PAC for. Andrew Bartlett
2011-10-04heimdal: handle referrals for 3 part DRSUAPI SPNsAndrew Tridgell1-1/+18
This handles referrals for SPNs of the form E3514235-4B06-11D1-AB04-00C04FC2DCD2/NTDSGUID/REALM, which are used during DRS replication when we don't know the dnsHostName of the target DC (which we don't know until the first replication from that DC completes). We use the 3rd part of the SPN directly as the realm name in the referral. Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>

check_constrained_delegation() hook is given A service should use S4U2Self instead of S4U2Proxy. Windows servers allow S4U2Proxy only to explicitly configured target principals. metze
2011-06-24HEIMDAL:kdc: pass down the server hdb_entry_ex to check_constrained_delegation()Stefan Metzmacher1-5/+19
This way we can compare the already canonicalized principals, while still passing the client specified target principal down to the backend specific constrained_delegation() hook. metze

For a normal TGS-REQ they're both signed with krbtgt key. But for S4U2Proxy requests which ask for contrained delegation, the keys differ. metze

2010-11-16heimdal Build ticket with the canonical server nameAndrew Bartlett1-1/+1
We need to use the name that the HDB entry returned, otherwise we will not canonicalise the reply as requested. Andrew Bartlett
2010-11-15heimdal Fetch the client before the PAC check, but after obtaining krbtgt_outAndrew Bartlett1-31/+30
By checking the client principal here, we compare the realm based on the normalised realm, but do so early enough to validate the PAC (and regenerate it if required). Andrew Bartlett
2010-11-15heimdal Fix handling of backwards cross-realm detection for Samba4Andrew Bartlett1-18/+48
Samba4 may modify the case of the realm in a returned entry, but will no longer modify the case of the prinicipal components. The easy way to keep this test passing is to consider also what we need to do to get the krbtgt account for the PAC signing - and to use krbtgt/<this>/@REALM component to fetch the real krbtgt, and to use that resutl for realm comparion.

2010-11-12heimdal Return HDB_ERR_NOT_FOUND_HERE to the callerAndrew Bartlett1-5/+22
This means that no reply packet should be generated, but that instead the user of the libkdc API should forward the packet to a real KDC, that has a full database. Andrew Bartlett

2010-10-02heimdal use returned server entry from HDB to compare realmsAndrew Bartlett1-1/+1
Some hdb modules (samba4) may change the case of the realm in a returned result. Use that to determine if it matches the krbtgt realm also returned from the DB (the DB will return it in the 'right' case) Andrew Bartlett
2010-09-29heimdal Add support for extracting a particular KVNO from the databaseAndrew Bartlett1-14/+37
This should allow master key rollover. (but the real reason is to allow multiple krbtgt accounts, as used by Active Directory to implement RODC support) Andrew Bartlett
2010-04-10s4:heimdal Create a new PAC when impersonating a user with S4U2SelfAndrew Bartlett1-4/+46
If we don't do this, the PAC is given for the machine accout, not the account being impersonated. Andrew Bartlett
2010-04-10s4:heimdal Add hooks to check with the DB before we allow s4u2selfAndrew Bartlett1-4/+36
This allows us to resolve multiple forms of a name, allowing for example machine$@REALM to get an S4U2Self ticket for host/machine@REALM. Andrew Bartlett

2009-06-18s4:kdc Allow a password change when the password is expiredAndrew Bartlett1-4/+4
This requires a rework on Heimdal's windc plugin layer, as we want full control over what tickets Heimdal will issue. (In particular, in case our requirements become more complex in future). The original problem was that Heimdal's check would permit the ticket, but Samba would then deny it, not knowing it was for kadmin/changepw Also (in hdb-samba4) be a bit more careful on what entries we will make the 'change_pw' service mark that this depends on.

2007-10-10r20640: Commit part 2/2Andrew Bartlett1-110/+228
Update Heimdal to match current lorikeet-heimdal. This includes integrated PAC hooks, so Samba doesn't have to handle this any more. This also brings in the PKINIT code, hence so many new files. Andrew Bartlett (This used to be commit 351f7040f7bb73b9a60b22b564686f7c2f98a729)
2007-10-10r19604: This is a massive commit, and I appologise in advance for it's size.Andrew Bartlett1-0/+1781
This merges Samba4 with lorikeet-heimdal, which itself has been tracking Heimdal CVS for the past couple of weeks. This is such a big change because Heimdal reorganised it's internal structures, with the mechglue merge, and because many of our 'wishes' have been granted: we now have DCE_STYLE GSSAPI, send_to_kdc hooks and many other features merged into the mainline code. We have adapted to upstream's choice of API in these cases. In gensec_gssapi and gensec_krb5, we either expect a valid PAC, or NO PAC. This matches windows behavour. We also have an option to require the PAC to be present (which allows us to automate the testing of this code). This also includes a restructure of how the kerberos dependencies are handled, due to the fallout of the merge. Andrew Bartlett (This used to be commit 4826f1735197c2a471d771495e6d4c1051b4c471)
