CentOS Linux release 8.4.2105
VERSION: 4.9.2, API_VERSION: 2.240

Prior to any updates I was at ver 8.2 of CentOS

The shared library was loaded and now I can start dirsrv.  THANKS!  That's definitely big a step in the right direction.  As I thought, my upgrade looks like it caused the version be too new for the existing dirsrv data.  I thought I had set my OS distro release version and that is my own dumb mistake...

IPA version error: data needs to be upgraded (expected version '4.9.2-4.module_el8.4.0+846+96522ed7', current version '4.8.4-7.module_el8.2.0+374+0d2d74a1')

I am thinking I could downgrade to get things up and running or do you suggest upgrading the data to work with the application version I have installed?

Knowing the distribution and version would help.

This missing shared library is provided by [free]ipa-server-trust-ad,
ipa-server, or something like it depending on the release.
