RTC-Acces through trusted domain

RDanylyschyn

Hello,

we've installed a three-tier Navision structure (following the documentation, with SPNs and so on). This works very fine in this domain. But we have a second domain (with domain-trust) where also RTC-Clients should be placed (with access to the NRT- and SQL-Server).
SQL- and NRT-Service have two different domain accounts with different SPNs
Here the following problems are appearing:

1. ClientUserSetting.Config:
AllowNTLM=false
ServicePrincipalNameRequired=true
leads to the message: 'Die Konfiguration des Dienstprinzipalnames (Delegierung) wurde nicht ordnungsgemäss festgelegt. URL der Serververbindung: 'net.[url=tcp://xxxx.yyy.com/DynamicsNav/Service...']tcp://xxxx.yyy.com/DynamicsNav/Service...'[/url]
(Sorry, I've the message in german only. A rough translation:
The configuration of the serviceprincipalname (delegation) is wrong. URL of the server connection...)

2. ClientUserSetting.Config:
AllowNTLM=true
ServicePrincipalNameRequired=true
leads to the message: The login failed when connecting to SQL Server zzzz.yyy.com.

I think the SPN-configuration is ok since in the first domain the RTC-access is ok.

Has anybody a similar installation working? Or any idea?
