Issue/Introduction

The slave PAM node (/Non-Master PAM node) is not able to join in the cluster with the Master Node.

Information from the log: 
WARN  [com.optinuity.c2o.util.SingletonMBeanLookupUtil] [ Initialization] Failed to create server connection to singleton MBean: c2o:service=OasisServerController in partition: abcdeaa44-fffy-9gggy-3857-faea0cd09yy99
javax.security.sasl.SaslException: Authentication failed: all available authentication mechanisms failed:
DIGEST-MD5: javax.security.sasl.SaslException: DIGEST-MD5: Server rejected authentication 

 

 

Environment

Release : 4.4

Cause

Root cause:  Missing jmx user details in "wildfly\domain\configuration\mgmt-users.properties" of the Master PAM node. Ideally, it should have the following entry.  jmxuser=<0xh0xh0xh0xh0xhx> ba (<0xh2>ba is dynamically generated.)

Resolution

Execute the following command to add the jmx user details

PAM\wildfly\bin>add-user.bat -u jmxuser -p CERTPASSWORD
Here <CERTPASSWORD> is the same password we use while installing the PAM installation. Master node PAM  Service restart is required to reflect the changes. Once it's up we can start the non Master PAM nodes.
