ODP.NET Core support for LDAP

Alex Keh-Oracle

Since a few people have asked me the same question through various channels and the answer is not straightforward, I created a thread to track the discussion. I've been recently asked whether ODP.NET Core ODP.NET Core supports LDAP.

The current answer is no, which is what you will find in the ODP.NET Core beta documentation. .NET Standard does not support System.DirectoryServices, which means ODP.NET Core does not support it either. However, MS has released the Windows Compatibility Pack (WCP), which does support System.DirectoryServices on Windows only. No cross platform support, but gives you LDAP support if running on Windows.

My question to ODP.NET Core users is whether you are looking for LDAP support for Windows only via WCP or you really want LDAP for Linux?

Hello

We recently migrated our version of Oracle to ORACLE 12C EXADATA. After this migration, developments using .NET were met only using full_framework. In the .net CORE, ODP.NET did not notice the connection via LDAP.

Do you know  if a version of ODP.NET is planned to fix this problem?

Alex Keh-Oracle

ODP.NET Core 19c is planned to support LDAP on Windows only.

There is currently no Microsoft capability for .NET Core LDAP support on Linux.

Thanks Alex

We use Windows servers in our applications.

Do you have a date estimate for this fix or the GIT link for testing 2.19c?

Very early 2019.

Hi Alex,

Is there any update on the release for LDAP support?

Alex Keh-Oracle

ODP.NET Core with LDAP support is packaged with Oracle DB 19c on Windows. When you see that released, you will be able to use ODP.NET Core from the Oracle DB client. We will release ODAC 19c soon after, which will have a stand along ODP.NET Core 19c.

Nice!

But wil this new 19c ODP.Net Core driver with LDAP support also be usable on an 12.2c database?

kind regards

Yes, 19c clients are supported all the way back to 11.2.

Hello

are there any news about this topic? I am not sure: is Oracle.ManagedDataAccess.Core 2.18.6 supporting LDAP (on Windows)? or not yet? Is it coming soon if not supporting yet? Would it be possible to get some kind of prerelease of 19c?

kind regards

ODP.NET Core 18c does not support LDAP, only 19c and higher. Oracle Database 19c on Windows is planned for release in mid-May. The ODP.NET Core version released with the DB on Windows will have LDAP support.

Hello Alex,

Do you have an specific date for the release that you are mentioning??

Because right now we are not able to configure the OracleManagentClient 2.18.6 , to force to use LDAP,

It's not working with sql.ora.

neither with app.config file

If you have a date, I really appreciated.

and thanks for the support

ODP.NET Core 19c is to be released with the DB 19c on Windows. The release management occurs outside my immediate team. We've been told the DB will be released at the end of this month with a possibility it could slip into very early June.
