Sun Identity Manager 8.1 Resources Reference

Administrators

Host resource adapters do not enforce maximum connections for an affinity administrator across multiple host resources connecting to the same host. Instead, the adapter enforces maximum connections for affinity administrators within each host resource.

If you have multiple host resources managing the same system, and they are currently configured to use the same administrator accounts, you might have to update those resources to ensure that the same administrator is not trying to perform multiple actions on the resource simultaneously.
