I inherited a cluster, setup properly, as far as I know. However, am getting the error:
"Bad Request — editTracker failed, reason='WARN: path=/masterlm/usage: Signature mismatch between license slave=//redacted// and this License Master. Please make sure that the pass4SymmKey setting in server.conf, "
when trying to point new systems to the license master.
I know the fix, but I don't know the plain-text pass4SymmKey phrase...
Best option is to create a new pass4SymmKey under the General Stanza for the Licensing server. You don't have to change the Cluster pass4symmKey. Once you change it for the License server, you can change it through out your cluster. And restart Splunk. This should take care of your issue.
