Hello,

I've already asked the below question in the Evolution mailing-list with
no response; maybe someone of the FreeBSD net folks can bring a bit
light into this.

Using the mentioned environment (on FreeBSD 8-CURRENT) I can't Subscribe
to Other user's Calendar in the Exchange server (don't blame me for
this, using Exchange :-)) . It fails with a more or less stupid message
about wrong password. 

I've watched with TCPDUMP what's happening when I access in the Menue
'Subscribe to Other user's Calendar': it does a DNS lookup for
kerberos.OCLC.org which is failing (yyy.yyy.yyy.yyy is our DNS server,
xxx.xxx.xxx.xxx is my laptop):


10:43:53.583797 IP xxx.xxx.xxx.xxx.34455 > yyy.yyy.yyy.yyy.53: 43976+ SRV?  
_kerberos._udp.OCLC.ORG. (41)
10:43:53.585520 IP yyy.yyy.yyy.yyy.53 > xxx.xxx.xxx.xxx.34455: 43976 NXDomain

10:43:53.586181 IP xxx.xxx.xxx.xxx.51100 > yyy.yyy.yyy.yyy.53: 48460+ SRV?  
_kerberos._tcp.OCLC.ORG. (41)
10:43:53.587866 IP yyy.yyy.yyy.yyy.53 > xxx.xxx.xxx.xxx.51100: 48460 NXDomain

10:43:53.588479 IP xxx.xxx.xxx.xxx.23102 > yyy.yyy.yyy.yyy.53: 46661+ SRV?

10:43:53.592087 IP yyy.yyy.yyy.yyy.53 > xxx.xxx.xxx.xxx.57028: 45174 NXDomain

10:43:53.592241 IP xxx.xxx.xxx.xxx.54405 > yyy.yyy.yyy.yyy.53: 45175+ AAAA?  
kerberos.OCLC.ORG. (35)
10:43:53.593850 IP yyy.yyy.yyy.yyy.53 > xxx.xxx.xxx.xxx.54405: 45175 NXDomain 
0/1/0 (85)

The domain OCLC.ORG is the part of my mail addr, i.e. my addr is 
<xxxxxx...@oclc.org>. 
The IT folks of my company gave me the hint that the above nslookup should not
be, for example, '_kerberos._udp.OCLC.ORG', but '_kerberos._udp.oa.OCLC.ORG'
(i.e. in the zone oa.OCLC.ORG) which indead is working with nslookup:

$ nslookup -type=SRV '_kerberos._udp.oa.OCLC.ORG'
Server:         yyy.yyy.yyy.yyy
Address:        yyy.yyy.yyy.yyy#53

Non-authoritative answer:
_kerberos._udp.oa.OCLC.ORG      service = 0 100 88 oadc5server.oa.oclc.org.
_kerberos._udp.oa.OCLC.ORG      service = 0 100 88 oadc01ewbe.oa.oclc.org.
_kerberos._udp.oa.OCLC.ORG      service = 0 100 88 oadc1server.oa.oclc.org.
_kerberos._udp.oa.OCLC.ORG      service = 0 100 88 oadc2server.oa.oclc.org.
...

Why Evo is asking for '_kerberos._udp.OCLC.ORG' and not for 
'_kerberos._udp.oa.OCLC.ORG'?

Thanks
