Description Chris Alavoine 2014-02-10 16:35:46 UTC
Hi there,

I create a new domain under main search domain in Forward Lookup Zones and then add a wildcard entry and (same as parent folder) entry pointing to an internal address. For instance in the domain example.com I create new subdomain test.example.com with wildcard entry for *.test.example.com.

test.example.com resolves fine, but any wildcard refuses to work.

I have been requested to file this bug report as it was reproducible by Marc Muehlfeld.

This is still an issue in 4.1.

Is this anywhere on the roadmap?
Comment 2 Hamza 2016-04-05 13:23:14 UTC
I still have this issue in version 4.3.4.

If I add a wildcard record to the zone (e.g. *.example.com) wc.example.com can be resolved. But if I add a wildcard to the subdomain (e.g. *.test.example.com), wc.test.example.com can not be resolved.

Record entry: *	A192.168.1.123

# nslookup wc.muc.pom
Name:   wc.muc.pom

# nslookup wc.test.muc.pom
** server can't find wc.test.muc.pom: NXDOMAIN

# nslookup *.test.muc.pom
Name:   *.test.muc.pom

Hi Hamza,


I've tested each version for wildcard support since 10.02.2014 when I first filed the bug report.

Hi Chris,

it seems that entries with '*' in sub-domains is not recognized as wildcard, but as an asterisk.

Unfortunately I can not use samba in a productive environment as long as this bug exists.

Hi Hamza,

Yes, that is the bug.

As a workaround I've put a standard BIND server in front of my Samba DC's which resolves any wildcard sub-domains I have, anything else is then forwarded onto the DC's. Not pretty but it works.

I too have this issue.  When adding a wildcard domain via windows DNS Manger or I get the record already exits.

When adding via samba-tool it adds it but not as a wild card but instead as an A entry for @.
