The issue occurred because the old LDAP CA was still linked to server certificates and cryptographic keys, preventing its deletion. We removed outdated dependencies, updated the Root and SSL CA certificates, and installed new server certificates. This resolved the problem.
Environment
All Vertica version
Situation
Old CA were not getting deleted.
Cause
The server certificates relied on an old CA certificate for authentication, and since the cryptographic keys were signed by this CA and still in use, the system prevented its deletion.
