I think there’s a critical issue with the product: you can’t add a second Active Directory server to prevent failures so that it can handle users via the LDAP protocol. Currently, the credential provider privacyidea doesn’t see the second Active Directory server. If there’s any advice on how to connect a second Active Directory server, I’d be happy to receive your help or advice.
Your question is not clear.
You do not connect the privacyIDEA Credential provider to an AD Server.
You connect the privacyIDEA Credential Provider to the privacyIDEA Server.
And you connect the privacyIDEA Server via Resolvers to an LDAP server like a windows domain controller.
So please state your question more precisely.
