2012-12-11s3:auth: fix dereference level in talloc checks in create_token_from_sid()Michael Adam1-2/+2
Commit c5b150b33fc54ed97dbd0736cc6f4c15977d6e70 introduced these checks. The current check "found_username == NULL" is wrong (we would segfault earlier in this case). We need to check *found_username == NULL instead as noted by Günter.

2012-12-10s3:auth: fix create_token_from_sid() to not fail in the winbindd caseMichael Adam1-2/+10
Commit 1c3c5e2156d9096f60bd53a96b88c2f1001d898a which factored the sid-based variant out of create_token_from_username() broke the case of a user handled by winbindd in that the "found_username" was set to NULL which caused the function to fail with NT_STATUS_NO_MEMORY further down. This patch fixes the function so that the case of found_username == NULL is cleanly separated from the NO_MEMORY case and the caller can provide the username in this case, if required. This fixes bug #9457. Signed-off-by: Michael Adam <obnox@samba.org> Autobuild-User(master): Volker Lendecke <vl@samba.org> Autobuild-Date(master): Mon Dec 10 18:18:54 CET 2012 on sn-devel-104

2012-11-12Use work around for 'winbind use default domain' only if it is setSumit Bose1-1/+2
Currently in smb_getpwnam() the NetBIOS domain name and the winbind separator character is always added to the user name returned by Get_Pwnam_alloc() if it does not contain the winbind separator character. As comments in the code indicates this is done as a work around if 'winbind use default domain' is set to yes in the samba configuration. This make sense if the option is set because otherwise the domain information is lost from the user name. But it causes errors if other services than winbind are used for user lookup, e.g. sssd. sssd can handle different kind of fully qualified user names as input, e.g. user@domain.name or DOM\user, but returns a canonical name, by default user@domain.name. While it would be possible to get around this issue with a special configuration either on the sssd or samba side I think the cleaner solution is to use the work around only if 'winbind use default domain' is set to yes which is what this patch does.

2012-07-19Revert "s3:auth make sure the primary group sid is usable"Andrew Bartlett1-30/+13
This reverts commit 00089fd74af740f832573d904312854e494a869e. The issue with this patch, which I did sign off on, is that for the domain member case, we already know that the SID is reasonable and valid, and we indeed rely on that, because we keep it as an additonal group anyway. The primary group is not so special that we need to do extra validation. Calling this function may put a user into the domain 'domain users' group, even if they are not in that group to start with.

This boolean was only set if the old machine account store (with an MD4 hash in it) was returned. We have not set that password type for years. If this call ever worked, it would store a plaintext password, so we could only ever be here if we had set a password using a version of Samba so old as not to store plaintext, and then never honered the flag anyway.

2012-07-03auth: Remove .get_challenge (only used for security=server)Andrew Bartlett4-116/+6
With NTLMSSP, for NTLM2 we need to be able to set the effective challenge, so if we ever did use a module that needed this functionlity, we would downgrade to just NTLM. Now that security=server has been removed, we have no such module. This will make it easier to make the auth subsystem async, as we will not need to consider making .get_challenge async.

This helps clarify the role of this structure and wrapper function. The purpose here is to provide helper functions to the lib/param loadparm_context that point back at the s3 lp_ functions. This allows a struct loadparm_context to be passed to any point in the code, and always refer to the correct loadparm system. If this has not been set, the variables loaded in the lib/param code will be returned. As requested by Michael Adam.

auth_netlogond was an important module in the development of the combined Samba 4.0, and was the first module to link smbd with the AD authentication store, showing that it was possible for NTLM authentication to be offloaded to the AD server components. We now have auth_samba4, which provides the full GENSEC stack to smbd, which also matches exactly the group membership and privileges assignment and which is supported and tested as part of the official Samba 4.0 release configuration.

2012-05-23Introduce system MIT krb5 build with --with-system-mitkrb5 option.Alexander Bokovoy1-2/+2
System MIT krb5 build also enabled by specifying --without-ad-dc When --with-system-mitkrb5 (or --withou-ad-dc) option is passed to top level configure in WAF build we are trying to detect and use system-wide MIT krb5 libraries. As result, Samba 4 DC functionality will be disabled due to the fact that it is currently impossible to implement embedded KDC server with MIT krb5. Thus, --with-system-mitkrb5/--without-ad-dc build will only produce * Samba 4 client libraries and their Python bindings * Samba 3 server (smbd, nmbd, winbindd from source3/) * Samba 3 client libraries In addition, Samba 4 DC server-specific tests will not be compiled into smbtorture. This in particular affects spoolss_win, spoolss_notify, and remote_pac rpc tests.
