2007-10-10r22844: Introduce const DATA_BLOB data_blob_null = { NULL, 0, NULL }; andVolker Lendecke1-2/+2
replace all data_blob(NULL, 0) calls. (This used to be commit 3d3d61687ef00181f4f04e001d42181d93ac931e)
2007-10-10r21845: Refactor the sessionsetupX code a little to allow usJeremy Allison1-31/+72
to return a NT_STATUS_TIME_DIFFERENCE_AT_DC error to a client when there's clock skew. Will help people debug this. Prepare us for being able to return the correct sessionsetupX "NT_STATUS_MORE_PROCESSING_REQUIRED" error with associated krb5 clock skew error to allow clients to re-sync time with us when we're eventually able to be a KDC. Jeremy. (This used to be commit c426340fc79a6b446033433b8de599130adffe28)

SID<->uid/gid cache. FIxes a bug in token creation (This used to be commit fa05708789654a8a34cb4a4068514a0b3d950653)
2007-10-10r16952: New derive DES salt code and Krb5 keytab generationGerald Carter1-9/+5
Major points of interest: * Figure the DES salt based on the domain functional level and UPN (if present and applicable) * Only deal with the DES-CBC-MD5, DES-CBC-CRC, and RC4-HMAC keys * Remove all the case permutations in the keytab entry generation (to be partially re-added only if necessary). * Generate keytab entries based on the existing SPN values in AD The resulting keytab looks like: ktutil: list -e slot KVNO Principal ---- ---- --------------------------------------------------------------------- 1 6 host/suse10.plainjoe.org@COLOR.PLAINJOE.ORG (DES cbc mode with CRC-32) 2 6 host/suse10.plainjoe.org@COLOR.PLAINJOE.ORG (DES cbc mode with RSA-MD5) 3 6 host/suse10.plainjoe.org@COLOR.PLAINJOE.ORG (ArcFour with HMAC/md5) 4 6 host/suse10@COLOR.PLAINJOE.ORG (DES cbc mode with CRC-32) 5 6 host/suse10@COLOR.PLAINJOE.ORG (DES cbc mode with RSA-MD5) 6 6 host/suse10@COLOR.PLAINJOE.ORG (ArcFour with HMAC/md5) 7 6 suse10$@COLOR.PLAINJOE.ORG (DES cbc mode with CRC-32) 8 6 suse10$@COLOR.PLAINJOE.ORG (DES cbc mode with RSA-MD5) 9 6 suse10$@COLOR.PLAINJOE.ORG (ArcFour with HMAC/md5) The list entries are the two basic SPN values (host/NetBIOSName & host/dNSHostName) and the sAMAccountName value. The UPN will be added as well if the machine has one. This fixes 'kinit -k'. Tested keytab using mod_auth_krb and MIT's telnet. ads_verify_ticket() continues to work with RC4-HMAC and DES keys. (This used to be commit 6261dd3c67d10db6cfa2e77a8d304d3dce4050a4)
2007-10-10r15523: Honour the time_offset also when verifying kerberos tickets. ThisGünther Deschner1-1/+6
prevents a nasty failure condition in winbindd's pam_auth where a tgt and a service ticket could have been succefully retrieved, but just not validated. Guenther (This used to be commit a75dd80c6210d01aff104a86b0a9d39d65f2c348)

2007-10-10r10907: Handle the case when we can't verify the PAC signature because theGünther Deschner1-5/+7

haven't broken krb5 ticket verification in the mainline code path, also need to check with valgrind. Everything now compiles (MIT, need to also check Heimdal) and the "net keytab" utility code will follow. Jeremy. (This used to be commit f0f2e28958cb9abfed216c71f291f19ea346d630)
2004-02-03Fix for a bug where the mutex could be left locked. Also remove theJeremy Allison1-146/+8
memory keytab code which has no effect. Driven by bug report from "Rob J. Caskey" <rcaskey@uga.edu>. Jeremy. (This used to be commit 4cb8facbf9fa6fa5233fdb363ceac4b304d263d4)
2004-01-06Fix segfualt caused by incorrect configuration. If lp_realm() was not set,Andrew Bartlett1-5/+9
but security=ADS, we would attempt to free the principal name that krb5 never allocated. Also fix the dump_data() of the session key, now that we use a data_blob to store that. Andrew Bartlett (This used to be commit 4ad67f13404ef0118265ad66d8bdfa256c914ad0)
2003-11-22Changes all over the shop, but all towards:Andrew Bartlett1-1/+1
- NTLM2 support in the server - KEY_EXCH support in the server - variable length session keys. In detail: - NTLM2 is an extension of NTLMv1, that is compatible with existing domain controllers (unlike NTLMv2, which requires a DC upgrade). * This is known as 'NTLMv2 session security' * (This is not yet implemented on the RPC pipes however, so there may well still be issues for PDC setups, particuarly around password changes. We do not fully understand the sign/seal implications of NTLM2 on RPC pipes.) This requires modifications to our authentication subsystem, as we must handle the 'challege' input into the challenge-response algorithm being changed. This also needs to be turned off for 'security=server', which does not support this. - KEY_EXCH is another 'security' mechanism, whereby the session key actually used by the server is sent by the client, rather than being the shared-secret directly or indirectly. - As both these methods change the session key, the auth subsystem needed to be changed, to 'override' session keys provided by the backend. - There has also been a major overhaul of the NTLMSSP subsystem, to merge the 'client' and 'server' functions, so they both operate on a single structure. This should help the SPNEGO implementation. - The 'names blob' in NTLMSSP is always in unicode - never in ascii. Don't make an ascii version ever. - The other big change is to allow variable length session keys. We have always assumed that session keys are 16 bytes long - and padded to this length if shorter. However, Kerberos session keys are 8 bytes long, when the krb5 login uses DES. * This fix allows SMB signging on machines not yet running MIT KRB5 1.3.1. * - Add better DEBUG() messages to ntlm_auth, warning administrators of misconfigurations that prevent access to the privileged pipe. This should help reduce some of the 'it just doesn't work' issues. - Fix data_blob_talloc() to behave the same way data_blob() does when passed a NULL data pointer. (just allocate) REMEMBER to make clean after this commit - I have changed plenty of data structures... (This used to be commit f3bbc87b0dac63426cda6fac7a295d3aad810ecc)

2003-09-03Try to add memory keytab support. It also includes much of the genericJim McDonough1-1/+141
keytab support code, but it won't be enabled until we add that to smb.conf. Adapted from the work of Guenther Deschner (gd@suse.com). Please hammer on this... (This used to be commit a26fa5bee24c73cd835f59bb18162ab07760d76a)

2003-08-15Fix memleaks.Volker Lendecke1-7/+11
Currently I'm compiling against MIT Kerberos 1.2.8. Anthony, you said you have a heimdal installation available. Could you please compile this stuff with krb and check it with valgrind? Thanks, Volker (This used to be commit d8ab44685994b302bb46eed9001c72c194d13dc8)
2003-08-14In ads_verify_realm, all we use in the ADS_STRUCT is theVolker Lendecke1-2/+2
auth.realm. So directly pass that instead of setting up and tearing down the ADS_STRUCT. Volker (This used to be commit ce5b8d2ec20fe1f4d3d1956020d88272fb84124a)

is not multi-process safe. Jeremy. (This used to be commit 9e0534a1b69bbd4f21b4925337cbab127d060fc6)
2003-07-29Typo on my part. I typed KRB5_KDB_BAD_ENCTYPE when I meant to type ↵Jeremy Allison1-1/+1
KRB5_BAD_ENCTYPE. Heimdal has the latter, not the former. Jeremy. (This used to be commit e8425df77c2e917c819592d93833a164ee3b5338)
2003-07-29Fix the build on Heimdal. KRB5_KDB_BAD_ENCTYPE doesn't exist on Heimdal, andJim McDonough1-1/+1
it's a different rc than KRB5_BAD_ENCTYPE (which exists on both MIT and Heimdal). This will just make the debug show up at level 3 always. Jeremy, you may want to revisit this, but it's probably not worth the hassle. (This used to be commit 4ff322ccf9c8485bcfe67e658d48f190f03547b0)

2003-07-25W00t! Client smb signing is now working correctly with krb5 and w2k server.Jeremy Allison1-1/+1
Server code *should* also work (I'll check shortly). May be the odd memory leak. Problem was we (a) weren't setting signing on in the client krb5 sessionsetup code (b) we need to ask for a subkey... (c). The client and server need to ask for local and remote subkeys respectively. Thanks to Paul Nelson @ Thursby for some sage advice on this :-). Jeremy.

2003-04-21Merge from HEAD - save the type of channel used to contact the DC.Andrew Bartlett1-1/+1
This allows us to join as a BDC, without appearing on the network as one until we have the database replicated, and the admin changes the configuration. This also change the SID retreval order from secrets.tdb, so we no longer require a 'net rpc getsid' - the sid fetch during the domain join is sufficient. Also minor fixes to 'net'.
