Hi @kdwofford,
In general this change should be transparent from AEM perspective, and I would not expect any changes on AEM level. However there are few areas in my opinion are worth to check, to confirm LDAP configuration on AEM side will not require updates.
- LDAP structure - if this will change during update AD update you may need reflect changes in attributes that are listed in your AEM configuration, e.g user id attribute has changed after AD update, new attribute will need to be set in configuration
- Connection - make sure host name, port etc has not change, in other case update AEM configuration
- SSL certificate - assuming your are using secure connection, check if certificate you are using has to be updated, or regenerated after AD upgrade
Last but not least please explore AEM documentation, to get full set of configuration options, and compare it, to options you are currently using. This should give you wider idea what you should verify in your specific implementation.
