Pre-requisites for configuring High Availability
Pre-requisites for configuring High Availability in ADManager Plus:
1. Ensure that both the instances of ADManager Plus:
a. Are running as a service.
b. Have the same build architecture (32-bit or 64-bit).
c. Are updated to the latest build.
d. Have the same context path.
e. Exist within the same domain and subnet. To verify this, ensure that both the servers fall within the same IP range. For instance, if you're connected to an IP range say 172.13.X.X, then the IP range of the primary server, standby server and the virtual IP address must also fall within the same IP range of 172.13.X.X.
2. In case an external database is being used, ensure that both the servers can access that database.
3. Ensure the installation of both the instances of ADManager Plus are shred on the network with the share name - ManageEngineADManagerPlus.
4. Ensure that the service account has full control access to both the installations of ADManager Plus.
5. Ensure that the service account configured to run the service of ManageEngine ADManager Plus on both instances is a member of the Domain Admin group.
