Hi All,

i ask for resolve my problem. This is a log after LUMT usage:

2013-07-09 09:45:10 INFO Starting LUMT platform...
2013-07-09 09:45:15 INFO LUMT platform started.
2013-07-09 09:45:15 INFO Processing user sip:user@damain.local... 2013-07-09 09:45:16 ERROR Error while processing user sip:user@damain.local: The target principal name is incorrect
2013-07-09 09:45:16 INFO Shutting down LUMT platform...
2013-07-09 09:45:16 INFO LUMT platform shut down.

I've configured everything how you explain in the Setup configuration. But now i can't go ahead.

Hi CodePlexTester85,

about your error log, i ask you: have you followed step by step the Setup Configuration described in a Documentation tabs ?

In substance, for a working LUMT "server" you have to:
  1. use LUMT tool in another server and not on you primary site server of Lync
  2. create, on your primary site server of Lync, an other UCMA application called LUMT using Lync Powershell Console following the procedure described in a Documentation guide
  3. install, using media of Lync Deployement, the component of Lync server in a the LUMT dedicated server
  4. hope for the best that everything goes well :-)
this is what i did. And however i get my error. So i can't help you much more.

Thanks - Started over on a fresh server and is working great now.

Great to know. It should be fine by following the documentation in CodePlex. If not, please tell me what step is wrong and I will fix it.

Hi Stefan,

have you a solution to resolve my problem ?
The line in log : "user sip:user@damain.local: The target principal name is incorrect" what exactly means ?

Could you provide more details on what your setup is?
If the server when LUMT is running a member of the Active Directory domain?

Hi Stefan,

i've setup my LUMT server following the documentation.
The only dubt about the current configuration is that in my infrastructure there is a principal domain and childs domain.
The Lync server and LUMT server are member of the same child domain, i ask if this can is the problem.

domain.local ( principal domain )
city.domain.local ( child domain ) ( lync server FQDN ) ( LUMT server FQDN )

This is the log if i try to update the contact list for any user:

2013-10-30 10:20:09 INFO Starting LUMT platform...
2013-10-30 10:20:12 INFO LUMT platform started.
2013-10-30 10:20:12 INFO Processing user sip:[email removed]...
2013-10-30 10:20:13 ERROR Error while processing user sip:[email removed]: The target principal name is incorrect
2013-10-30 10:20:13 INFO Shutting down LUMT platform...
2013-10-30 10:20:13 INFO LUMT platform shut down.

I don't know if LUMT Platform can work across the domain hierarchy, though the entire Lync infrastructure can work across the multiple domain hierarchy.

I have installed version and I still get a similar error above.

Seems to me a certificate mismatch issue, but the default cert on our FE server is the FQDN of the server joined to AD also the common name of the certificate. This is Skype for Business Server 2015 Standard Edition. Running LUMT on one of our SDN managers (using http), but added to our topology as a trusted application server per the documentation here.

This may be related to a certificate issue, you must give more information about your setup:
  • Did you installed binaries like described in the last step of the Setup documentation?
  • On your LUMT server, what is the information for Subject Name and Subject Alternative Name fields for the certificate?
  • On your SfB server, what is the information for Subject Name and Subject Alternative Name fields for the certificate used by the SfB server?
  • Do you use have all DNS records set up to allow automatic discovery of the SfB server (,, etc...)?
