This post is part of "Overview of NAV-specific SQL features for application consultants".





Microsoft Dynamics NAV requires two extended stored procedures from xp_ndo.dll to exist on SQL Server if Windows logins are used. If these extended stored procedures do not exist, you will get this error when trying to log on using Windows Authentication:


---
The extended stored procedure xp_ndo_enumusersids in the library file xp_ndo.dll, is not available on the LOHNDORF1 server. Until this procedure and library have been added, it will not be possible to connect to this server from Microsoft Dynamics NAV with Windows Authentication, but you will still be able to connect with Database Server Authentication. You can read more about adding this extended stored procedure in the help pages on the product CD. Follow the hyperlink to the readme.txt file on the Servers page under the Documentation section of SQL Server.


---





When this happens you have two options: Use Database Authentication instead, or create the extended stored procedures on the SQL Server. a normal installation of a NAV client will create these procedures automatically, which is why in most cases you don’t need to do it. But if for some reason it was not created, then this is how to do it manually:


1) From the product DVD, open the folder sql_esp, and run the file xp_ndo.exe to extract the file xp_ndo.dll somewhere you your disk. Then copy it into this folder on your SQL Server (on SQL 2008): C:Program FilesMicrosoft SQL ServerMSSQL10.MSSQLSERVERMSSQLBinn. Remember, copying files into the “Program Files”-folder requires administrative privileges on Vista and Windows2008, which is why you should extract the file to a different folder first, and then copy it into this location.



2) Open SQL Server Management Studio. Extend Databases -> System Databases -> master -> Programmability. Right click on “Extended stored procedures”, and select “New extended stored procedure”.



3) Name it xp_ndo_enumusersids, and in the DLL field, select the full file and path for xp_ndo.dll (on SQL Server 2008 C:Program FilesMicrosoft SQL ServerMSSQL10.MSSQLSERVERMSSQLBinnxp_ndo.dll):





4) Assign permissions to the public role: In the Extended Stored Procedures properties, click on “Permissions”, then “Search”. Type in “Public”, and click OK. Then assign Execute permissions to Public:





5) Finally, repeat the previous steps and make another extended stored procedure which is exactly identical, except this one must be called xp_ndo_enumusergroups instead of xp_ndo_enumusersids.


You should now have two extended stored procedures, and should be able to use Windows login from NAV.
