Edit the "jdk.jar.disabledAlgorithms" section of the java.security file and remove the weak algorithm that DRAC is using, so that it will not be blocked.
The file is located here: C:\Program Files (x86)\Java\jre1.8.0_131\lib\security\java.security
This workaround should be considered "at your own risk" and is not officially endorsed or supported by One Identity.
The solution is to upgrade the version of iDRAC software on the appliance, however, this may require an RMA replacement of the hardware. Please discuss with One Identity Support to determine the best course of action.
