Adobe acrobat DC not showing keychain digital IDs

[fmarin]

In preferences / signatures / identities & trusted certificates / digital IDs, I am supposed to see the ones I have registered in my keychain app, but window shows empty.  This causes that I can't sign a PDF document as I need a digital ID for this purpose.

I have installed some valid certificates in keychain but it seems that acrobat can't access them or does not recognize them.

I am using MAC OS Catalina 10.15.2 with Adobe Acrobat Reader DC 2019.021.20058

Any hint on this would be appreciated.

Please check that your digital ID is valid for the scope, meaning that it needs to have key usage and extended key usage in line with Acrobat's requirements. See https://www.adobe.com/devnet-docs/etk_deprecated/tools/DigSig/changes.html under 11.0.09. If the ID is not aligned with the KU/EKU requirements it would not show up in the list of Digital IDs.
