3-Tier setup problem with access delegation

Ian_WilsonIan_Wilson Member Posts: 25
edited 2009-08-19 in NAV Three Tier
I am following the Walkthrough: Installing the Three Tiers on Three Computers topic from the nav_install.chm that is on the DVD.

I have the DB, Nav Server and Nav Client machines setup running Win2k8, Win2k8 and Vista.

I have configured a Domain Account for the Nav Server service to run under and ran the command to Create a Service Principal Name. I have edited the ClientUserSettings.config and added the key as directed (<add key="DelegationInfo" value="DomainUser"></add>).

I then come to the section of the help file headed "Delegating Access to the SQL Server Service", at step 10 it says "In the list of services, click MSSQLSvc, the SQL Server service." - the problem I have is that MSSQLSvc is not listed.

It doesn't help that the online version of the walkthrough (http://msdn.microsoft.com/en-us/library/dd301254.aspx) is slightly different.

Can anyone offer any advice as to where I may have gone wrong please?

    Try adding these to ClientUserSetting.config:
    <add key="AllowNtlm" value="false" />
    <add key="ServicePrincipalNameRequired" value="true" />
    
    Also be sure that you edit the file in the Documents and Settings\<username>\Local Settings\Application Data\Microsoft\Microsoft Dynamics NAV directory.

    Also if not work - check your spn's.

    Give this a shot:

    Open up the user you created to run the service in Users and Computers
    Select the Delegation tab
    Set it to “Trust this user for delegation to specified services only"
    And set it to “use Kerberos only”
    Then press “Add”
    Find the user you created to run the service (and created the SPN for)
    You should see the MSSQLSvc for the user there to add.

    If you don't then you may not have created the right SPN for the user. You can use ADSIEdit.msc to see what service principle names are for the user.

    Here are examples of the SPN I created:
    MSSQLSvc/domain.servername
    MSSQLSvc/domain.servername:1433

    Good luck!

    Thanks for the suggestions. I will give them a try.

    One thing I should have added to the original post is that I am trying to use SQL Server 2008.

    Will update when I have had chance to test this further.

    I am doing all of this on some Hyper-V machines, so I rolled back to bare Win2k8 and started again.

    I am just stuck at the same point.

    I have set up a Domain User called NavServer and used the following command to create the SPN (test domain is called marvel)
    C:\Users\Administrator.PDC>setspn -A DYNNAV-SERVER_DynamicsNAV/DYNNAV-SERVER.mar
    vel.company.com:7046 marvel\NAVServer
    Registering ServicePrincipalNames for CN=NAVServer,CN=Users,DC=marvel,DC=company
    ,DC=com
            DYNNAV-SERVER_DynamicsNAV/DYNNAV-SERVER.marvel.company.com:7046
    Updated object
    

    I can see the SPN in ADSI Edit.



    Yet when I get to step 10 in the "To delegate access to the SQL Server Service" of the walkthrough (when I have right-clicked DYNNAV-SERVER and on the Delegation tab have clicked "Trust this computer for delgation to specified services only" and "Use Kerberos only" and clicked [Add] and added DYNNAV-SQL-SERVER) I see the list of "Available services:" shown here.



    MSSQLSvc is not there! ](*,)

    Are you trying to set up NAV with the NAV service running as Network Service or a domain user account? When you specify 'Trust this computer for delegation to the specified services only', this implies that you have gone to properties on the computer that is running the NAV service. If you have the NAV service running as Network Service, you should go to the properties of the computer running NAV in active directory. If you have the service running as a domain user (as the walkthough explains), you should go to properties on the user account for the NAV service in active directory.

    Earlier you said you were following the walkthrough, so I will assume this is the case. When you specify 'Trust this user for delegation to the specified services only' in AD, in the dialog when you press Add, you need to specify the SQL Server service account.

    Let's assume your NAV service is running as a domain user called marvel\NAVServer and SQL Server services run as a domain user called marvel\SqlServer.

    You should create SPNs for SqlServer as follows:

    setspn -a MSSQLSvc/SQL-SERVER.marvel.company.com marvel\SqlServer
    setspn -a MSSQLSvc/SQL-SERVER.marvel.company.com:1433 marvel\SqlServer

    where SQL-SERVER is the name of the computer where SQL Server is running.

    The SPN you gave for NAV looks good, assuming you are using NAV 2009 RTM (not hotfixed, not SP1 CTP), NAVServer is a domain user account, and DYNNAV-SERVER is the name of the computer running the NAV service.

    Now, you should be able to go into the AD snap in and find the user NavServer. Go to properties, then delegation. Press Add, then Users or Computers... and enter SqlServer. You should then see a list of services with SPNs that run under the account SqlServer - this should include MSSQLSvc.

    Thanks. None of those steps are in the Walkthrough.

    The SQL Database Engine User is called SQLDBE. I have set the SPNs up as per the suggestion.
  • Ian_WilsonIan_Wilson Member Posts: 25
    I now have the delegation set up correctly I think?

  • Ian_WilsonIan_Wilson Member Posts: 25
    I have now set up the SQL Server Login and DB User for domain account NAVServer.

    Now, when I run the RTC on DYNNAV-CLIENT, it pauses for about a minute and then shows this error message.



    I have checked on the DYNNAV-CLIENT for the ClientUserSettings.config files.

    There are two;

    \\dynnav-client\c$\ProgramData\Microsoft\Microsoft Dynamics NAV
    \\dynnav-client\c$\Users\administrator\AppData\Local\Microsoft\Microsoft Dynamics NAV

    Both contain this;
    <?xml version="1.0" encoding="UTF-8"?>
    <configuration>
    	<appSettings>
    		<add key="Server" value="DYNNAV-SERVER"></add>
    		<add key="ServerInstance" value="DynamicsNAV"></add>
    		<add key="ServerPort" value="7046"></add>
    		<add key="DelegateInfo" value="DomainUser"></add>
    	</appSettings>
    </configuration>

    I also have set the permissions on the NAV Server Folder.

    Your setup of the SPNs and delegation look correct.

    I think NAV will connect to SQL Server using TCP/IP if you set NetType = Default in the service config. Therefore, check whether TCP/IP is enabled on SQL Server using the SQL config management tool - I often forget this. Also, you will need to open the port (1433 by default) on the firewall.

    Since you created the SPN for NAV using a fully qualified name, I think you need to also specify a fully qualified name in the clientUserSettings.config file, e.g. <add key="Server" value="DYNNAV-SERVER.marvel.company.com"></add>.

    Also, after you make changes to SPNs you should restart the affected services.

    TCP/IP is enabled on the SQL Server, the firewall on all 3 machines is turned off.

    I changed the clientUserSettings.config file (both of them on the Client tier machine) to contain <add key="Server" value="DYNNAV-SERVER.marvel.company.com"></add>.

    The 3 machines can all resolve each other's name and ping each other.

    Now when I run the RTC on the Client tier PC, I get this after a minute or so pause:



    If I click [Yes] to try again, the same message is displayed after a minute or so.

    If I click [No], I am shown this:



    If I click [Connect], after a minute or so pause, I am shown this:



    So, slightly different, but back to where I was last week ](*,)
  • mihail_kolevmihail_kolev Member Posts: 379
    what about "DYNAV-SERVER.marvel.com/DynamicsNAV"
    -Mihail- [MCTS]
  • Ian_WilsonIan_Wilson Member Posts: 25
    That produces a similar error, with just the change of server name.

  • Ian_WilsonIan_Wilson Member Posts: 25
    I saw from the MSDN article on trouble shooting connection problems (http://msdn.microsoft.com/en-us/library/dd983822.aspx) that Names Pipes needs to be enabled as well.

    It wasn't on my server, so I enabled it and still get the same problem ](*,)
  • Ian_WilsonIan_Wilson Member Posts: 25
    Here is the latest.

    I have set up a 4th VM called Nav2009AllTier and installed SQL and Nav Server and both of the clients on to it using Install Demo option from the installation DVD.

    So I now have 4 machines
    • DYNNAV-SQL - The SQL Server, Win2k8 and SQL2k8
    • DYNNAV-Server - The Navision middle tier server, Win2k8
    • DYNNAV-Client - The client tier, WinVista
    • NAV2009AllTier - New server, Win2k8 and SQL2k8

    What I can do with the Classic Client

    On DYNNAV-Client I can open CRONUS on DYNNAV-SQL and on Nav2009AllTier using server name DYNNAV-SQL and Nav2009AllTier respectively.

    On NAV2009AllTier I can open CRONUS on DYNNAV-SQL using Server name DYNNAV-SQL and I can open CRONUS on Nav2009AllTier using Server name Nav2009AllTier or localhost.

    What I can do with the RTC

    On Nav2009AllTier I can open CRONUS on Nav2009AllTier using Server name Nav2009AllTier/DynamicsNAV

    On DYNNAV-Client I can open CRONUS on Nav2009AllTier using Server name Nav2009AllTier/DynamicsNAV

    What I cannot do with the RTC

    I cannot, on DYNNAV-Client or Nav2009AllTier, open Cronus using Server name DYNNAV-Server/DynamicsNAV

    I cannot see anything that looks related in the Event Logs on DYNNAV-SQL or DYNNAV-Server and there is nothing NAV related in the SQL Server's log apart from an entry stating that spidxx is using xp_ndo_x64.dll to execute one of the ESPs (I am guessing this is when I connected with the Classic client).

    I would have expected to see the fully qualified name in your error message, e.g.
    Message: A server was not found at "net.tcp://dynnav-server.marvel.company.com:7046/DynamicsNAV/Service". Either the URL is incorrect or the server is currently not available.
    
    The client should be able to connect with either netbios or fully qualified names, even if authentication later fails once the connection has been established.

    Further down in the stack trace we can see a SecurityNegotiationException, then an AuthenticationException, then eventually a Win32Exception with the message 'The target principal name is incorrect'. This suggests to me that although it looks like you simply can't connect to the server, actually you are having a problem negotiating an authentication scheme.

    Before you try anything else, please confirm that you are using NAV 2009 without any hotfixes applied, and that you are not using the SP1 CTP2 release.

    Since your other settings look good I wonder if you have accidentally created duplicate SPNs. I would recommend skimming through this guide to troubleshooting Kerberos errors: http://technet.microsoft.com/en-us/library/cc728430(WS.10).aspx.

    In particular, try:

    I feel your pain!

    I am having EXACTLY the same issue as you. On VMware....

    Let me know if you come across anything, and if I make a tweak and get it to work I'll do the same.

    -Edit.....
    Forgot to say, I changed my Client config file to point to the IP Address instead of FQDN and get the error

    Microsoft Dynamics NAV

    The login failed when connecting to SQL Server SRVVANSQL1.
    OK
