2010-06-02s3: Allow previous password to be stored and use it to check ticketsMatthieu Patou1-37/+58
This patch is to fix bug 7099. It stores the current password in the previous password key when the password is changed. It also check the user ticket against previous password. Signed-off-by: Günther Deschner <gd@samba.org>
2010-05-11s3:kerberos Return PAC_LOGON_INFO rather than the full PAC_DATAAndrew Bartlett1-5/+20
All the callers just want the PAC_LOGON_INFO, so search for that in ads_verify_ticket(), and don't bother the callers with the rest of the PAC. This change makes sense on it's own (removing boilerplate wrappers that just confuse the code), but it also makes it much easier to implement a matching ads_verify_ticket() function in Samba4 for the s3compat proposal.

2009-02-02fix for commit d96248a9b46 which broke Heimdal buildsBjörn Jacke1-0/+6
2009-02-01Add two new parameters to control how we verify kerberos tickets. Removes ↵Dan Sledz1-17/+112
lp_use_kerberos_keytab parameter. The first is "kerberos method" and replaces the "use kerberos keytab" with an enum. Valid options are: secrets only - use only the secrets for ticket verification (default) system keytab - use only the system keytab for ticket verification dedicated keytab - use a dedicated keytab for ticket verification. secrets and keytab - use the secrets.tdb first, then the system keytab For existing installs: "use kerberos keytab = yes" corresponds to secrets and keytab "use kerberos keytab = no" corresponds to secrets only The major difference between "system keytab" and "dedicated keytab" is that the latter method relies on kerberos to find the correct keytab entry instead of filtering based on expected principals. The second parameter is "dedicated keytab file", which is the keytab to use when in "dedicated keytab" mode. This keytab is only used in ads_verify_ticket.

2008-03-10Use a separate tdb for mutexesVolker Lendecke1-9/+6
Another preparation to convert secrets.c to dbwrap: The dbwrap API does not provide a sane tdb_lock_with_timeout abstraction. In the clustered case the DC mutex is needed per-node anyway, so it is perfectly fine to use a local mutex only. (This used to be commit f94a63cd8f94490780ad9331da229c0bcb2ca5d6)

2007-10-10r23474: Here's a small patch that disables the libkrb5.so replay cacheGerald Carter1-39/+63
when verifying a ticket from winbindd_pam.c. I've found during multiple, fast, automated SSH logins (such as from a cron script) that the replay cache in MIT's krb5 lib will occasionally fail the krb5_rd_req() as a replay attack. There seems to be a small window during which the MIT krb5 libs could reproduce identical time stamps for ctime and cusec in the authenticator since Unix systems only give back milli-seconds rather than the micro-seconds needed by the authenticator. Checked against MIT 1.5.1. Have not researched how Heimdal does it. My thinking is that if someone can spoof the KDC and TDS services we are pretty hopeless anyways.

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.

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.
