Windchill OIDC

Is anyone using / testing OIDC on Windchill 13.0.2.x yet? Followed the instructions, but Apache fails to load auth_openidc_module.

Kind of stumped here, when manually running httpd.exe, I get: Cannot load modules/mod_auth_openidc.so into server: The specified module could not be found.

Server root is proper, permissions look good, and the license file for auth_openidc_module is in the proper location. (only CS reference on PTC for OIDC/Windchill)

So it turned out the issue was related to a corrupted module file (mod_auth_openidc). Copied form another installation and it worked fine.

Hi @jbailey ,

the error message is very clear about missing the mod_auth_openidc module.
Which operating system are you using?

Which installation for the mod_auth_openidc module did you use?

Did you copy the mod_auth_openidc module into the modules subdirectory of the PTC supplied Apache?

Oh the message is clear, however everything is where it should be. In Windchill 13.0.2.0 mod_auth_openidc is provided by PTC and in the modules folder, with the commercial license in the conf folder. Everything is being setup/deployed as described in the PTC support center for 13.0.2

This is a Windows implementation.

Sorry, I was not aware of the PTC provided OIDC support in Windchill 13.0.2 as we are still on 12.
I did all the OIDC installations manually and on Linux.

Anyhow, there has to be a reason why the module cannot be loaded. As far as the PTC documentation shows on the Linux platform the module itself is loaded indirect via the LD_LIBRARY_PATH environment variable and not the direct path to the file. So maybe this helps for further investigations.

Update: This issue reappeared with the latest WC 13.0.2 CPS, and it seemed like the module file that was modified in October and delivered was in fact corrupted. I was finally able to get PTC to reproduce the issue, and then R&D was also able to reproduce. If you use the module file from the previous prior to the 13.0.2.2 CPS, that is a quick fix (use this advice at your own risk)
