Config sync problems after modifying cert in default client-ssl profile when the profile is already active and in use on members in a high availability configuration.
After config sync, units in the sync group have different cert/key settings for client-ssl profiles. You can see this in the inherit-certkeychain setting, which changes from 'true' to 'false' after syncing the configuration with the changed default value.
Modify cert in default client-ssl profile and perform a config sync operation.
1. Remove client-ssl definitions from bigip.conf on each unit. 2. Reload the config. 3. Synchronize the config.
The system now correctly syncs the default client-ssl profile that was modified with a new cert and key, so the active and standby unit configurations now have the correct cert/key settings after config sync.
