This is really weird : If I manually run : dig
_ldap._tcp.my_forst_name.com SRV
I can see the 4 AD servers in ANSWER, AUTHORITY and ADDITIONAL SECTION
If I use : pool.default.serverset.srvrecord.service = ldaps
In the logs I see this : "An error occurred while attempting to query DNS in order to
retrieve SRV records with name '_ldaps._tcp.my_forest_name.com':"
The same happens with : dig @any_of_the_4_AD_server
_ldap._tcp.my_forest_name.com SRV
So why dig can resolve it but not ovirt ?
If I understand correctly, you misunderstood meaning of
'vars.dns' variable.
This variables says what DNS server(s) should be used to send DNS
queries, instead of the
default one from /etc/resolv.conf.
So if you specify:
vars.dns =
dns://ad_server.mydomain.com
then aaa-ldap do following:
$ dig @ad_server.mydomain.com
_ldap._tcp.'pool.default.serverset.srvrecord.domain' SRV
if you remove 'vars.dns' varibale then aaa-ldap does following:
$ dig _ldap._tcp.'pool.default.serverset.srvrecord.domain' SRV
so default DNS servers are used.
Interesting, now I understand better...
In config files no. The correct approach is configure DNS properly.
Because SRV record
provides you port on which that service operates. So I would suggest you
either create new SRV record named 'ldaps' with port 636(in your AD
DNS), or use startTLS with port 389.
"ldaps" is also a kind of conventional "microsoft SRV record" like
_ldaps_tcp ?
With startTLS I didn't have any success (and I don't really get why) :
