Why are there fabric-maven-proxy related "Access denied" error messages in JBoss Fuse logs?

Issue

• While trying to modify the JAAS realm in Fuse Fabric to make use of the LDAP Login module as described in the below documentation link [1].

• Unable to upload bundle to local Maven repository via Fabric Maven proxy.

• Fuse is running a Fabric server, currently on the same machine, and would like to deploy the blueprint XML as a bundle into Fabric repository via Fabric's Maven proxy so that it can be added into a profile via fmc.

• While trying to run mvn deploy on a Maven bundle project, the below error is observed:
