* Avoid overriding default ccache for ads operations.Simo Sorce2012-09-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | Avoid overriding default ccache for ads operations. Nowadays various samba components may need to use GSSAPI and a default cred cache to perform their tasks. This code was completely overriding the whole process default ccache name, thus altering the current credentials and sometimes hijacking them (or getting preemptively hijaked). By using gss_krb5_import_cred we can instead use a private ccache (necessary sometimes to use a different set of credentials fromt he default cifs/fqdn@realm one, for example when contacting foreign DCs using trust credentials) that does not affect the rest of the process. For the kerberos versions which don't have gss_krb5_import_cred we fallback to temp override of KRB5CCNAME and gss_acquire_cred.

| | | | | | | | | | When parsing a SPNEGO session setup retry (falling back from KRB5 to NTLMSSP), we failed to parse the ASN1_ENUMERATED negResult in the negTokenTarg, thus failing spnego_parse_auth() completely.

| | | | | | | | | | | | | | | | | | | | | | - We ran across a bug joining our Samba server to a Win2K domain with LDAP signing turned on. Upon investigation I discovered that there is a bug in Win2K server which returns a duplicated responseToken in the LDAP bindResponse packet. This blob is placed in the optional mechListMIC field which is unsupported in both Win2K and Win2K3. You can see RFC 2478 for the proper packet construction. I've worked with metze on this to confirm all these finding. This patch properly parses then discards the mechListMIC field if it exists in the packet, so we don't produce a malformed packet error, causing LDAP signed joins to fail. Also attached is a sniff of the domain join, exposing Win2Ks bad behavior (packet 21). - (I've just changed the scope of the DATA_BLOB mechList) metze (This used to be commit 200b5bfb8180af09446762e915eac63d14c6c7b0)

* r21240: Fix longstanding Bug #4009.Günther Deschner2007-10-101-2/+4
| | | | | | | | | | | | | | | | | | For the winbind cached ADS LDAP connection handling (ads_cached_connection()) we were (incorrectly) assuming that the service ticket lifetime equaled the tgt lifetime. For setups where the service ticket just lives 10 minutes, we were leaving hundreds of LDAP connections in CLOSE_WAIT state, until we fail to service entirely with "Too many open files". Also sequence_number() in winbindd_ads.c needs to delete the cached LDAP connection after the ads_do_search_retry() has failed to submit the search request (although the bind succeeded (returning an expired service ticket that we cannot delete from the memory cred cache - this will get fixed later)).
