Hi all...
I have to create a view that shows data from a OID (Oracle Internet Directory).
I created a linked server, that uses "OLE DB Provider for Microsoft Directory Services" and tried to query by LDAP. But it does not work.
Anyone with experience?
Thanks

I googled "SQL server linked server to "Oracle Internet Directory" " with no luck at all;

how often does the data change in the "Oracle Internet Directory"? is it something you could export to text, and import into SQL via BULK INSERT or SSIS as a table instead of a view, refreshing it at intervals appropriate to the amount of changes that occur? if it's pretty much static, it doesn't really need to be a view to a linked server right? if it changes a lot, i would look deeper into creating the linked server to do it.

Thanks for your reply.

This OID changes daily. In the end this should become the source for a synchronization between the OID and MSSQL-Data. And this synchronization should run unattended several times per day.

... tried to query by LDAP. But it does not work.

Would you mind in defining "does not work"?

OID is supported by an Oracle database therefore a SQL Server side linked server pointing to the underlying Oracle database - provided the connection presents itself with the right credentials, should suffice to provide the needed access.

I don't mind defining... 🙂

I get errors like:

The provider indicates that the user did not have the permission to perform the operation.

Access to the remote server is denied because no login-mapping exists.

But anyway, I guess it is just not possible to access OID by "OLE DB Provider for Microsoft Directory Services".

I can't access the Oracle-DB, the company policy does not allow that. I have to access OID by LDAP.

Sounds like you're not using the right credentials to the OID.

Sounds like you're not using the right credentials to the OID.

Yes, but I can login to OID with these credentials with a LDAP Browser.

This is what I have to use as value for the user name: cn=clientele_dev_01,cn=tech_users,cn=dev_env,o=******,c=ch

I guess that OID can't handle the credentials if I'm using the ADsDSOObject to connect. ... I dont't know.

I tried for days to find a working solution. I would like to know if anyone ever accomplished to read data from OID into a view.

Right, your LDAP credentials may be fine. But SQL Server isn't connecting to the OID Linked Server using LDAP. I know the provider you're using should technically be LDAP b/c that's what AD uses also but I wouldn't trust MS LDAP and Oracle LDAP to speak to each other easily.

I know it mentions SQL 2005, but have you tried something like this: MSDN.

Edited for clarity.

Thank you for this link but I still can not find a working solution for MSSQL-OID.

I have found no solution for this.
