2024-09-29lib/addns: match additional names in a non case insensitive wayStefan Metzmacher1-1/+5
Sometime proxy dns servers mess up the case of parts of the name... So we should match with strequal() instead of strcmp(), which results in much less dns packets on the wire...

This issues the "query" for SRV records site-aware and siteless. If there are SRV records returned without IP addresses, it will issue A and AAAA requests, waiting up to async_dns_timeout seconds.

2012-05-23libcli/dns: make 'clidns' private library out of DNS code in WAF buildAlexander Bokovoy1-1/+1
After consolidating DNS resolver code to lib/addns, there is one piece that still needs to be moved into a common DNS resolver library: DNS_HOSTS_FILE subsystem. Unfortunately, direct move would require lib/addns to depend on libcli/util/{ntstatus.h,werror.h} (provided by errors subsystem). In addition, moving libcli/dns/* code to lib/addns/ would make conflicting the dns_tkey_record struct. The conflict comes from source4/dns_server/ and is due to use of IDL to define the struct. lib/addns/ library also provides its own definition so we either need to keep them in sync (rewrite code in lib/addns/ a bit) or depend on generated IDL headers. Thus, making a private library and subsystem clidns is an intermediate step that allows to buy some time fore refactoring.
2012-05-23Introduce system MIT krb5 build with --with-system-mitkrb5 option.Alexander Bokovoy3-5/+5
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.
