Authentification between Dagent & Sendmail and remote Kopano Core server fails

That looks to me either like a permission problem

Yes, would have said the same. For easier testing I would suggest to use kopano-admin/kopano-cli instead of the dagent. The ssl options are named the same for all services, so you can easily specify the dagent.cfg for admin. once you get your users listed all should be good for dagent as well.

@thctlo Thank you. I believe this does not work, since DAgent is hosted on a different server? Am I right that you are assuming it is on the same server?

kopano-cli

Hello, I admit that you suggestion is not yet 100% clear to me (sorry for that and potential errors!). I verified that the ssl connecton from the DAgent -> Core Server works by entering:

openssl s_client -connect kopano.intranet.XXXXXX.de:237

Resulting in:

...

When testing “kopano-admin -vvvv -h kopano.intranet.XXXXX.de:237 -c /etc/kopano/dagent.cfg -l” on the DAgent server (targeting Core server) I recieve:

[error  ] gsoap connect: ()
[error  ] virtual HRESULT M4LMsgServiceAdmin::ConfigureMsgService(const MAPIUID*, ULONG_PTR, ULONG, ULONG, const SPropValue*): MSGServiceEntry failed: network error (80040115)

The server is not running, or not accessible through "kopano.intranet.XXXXX.de:237".
Using the -v option (possibly multiple times) may give more hints.

and the “recieving” kopano core server log states:

Mon Apr 30 12:32:50 2018: [debug  ] Accepted incoming SSL connection from 172.16.1.18

Am I doing something wrong? Cheers

Looks quite similar to: https://forums.zarafa.com/showthread.php?7734-Remote-Access-to-Zarafa-Server-with-dagent-via-https-does-not-work

Unfortunately some parts of the the forum seems to be “hidden”…

And another link: https://www.cubewerk.de/2015/01/09/zarafa-port-237-ssl-ssl_accept-failed-in-soap_ssl_accept/

But still do not find my error (besides required/insisting to use my own self-signed CA files :-/)

Hi @fixundfertig123 ,

I’d recommend to open a support case. Our support staff can have a look at your exact certificate files and through this better identify what needs to be changed.

Ps: what do you mean with “hidden” in regards to the old forum? That thread seems complete to me.

fixundfertig123

Hi @fbartels , thanks I will!

to me the zarafa forum looks like the code insertion are somehow missing?!? I attached a screenshot:

What do you think?

thctlo

@fixundfertig123 Yes, correct i run Dagent on the same server.

fbartels

@fixundfertig123 ah. did not notice this. The forum was modified a few weeks ago to be completely read-only maybe inline quotes were removed in that process.

fixundfertig123

@fbartels Okay, thats quite sad, it was a good source of knowledge… Maybe it can be readded? Thanks for your help anyway!
