Any help in how can I fix it? I read some related tickets, but i could not figure out my mistake.

@Gustavo The error message is not very descriptive. This means that you’re trying to connect a node that is not defined in the plugins.security.nodes_dn.

Try this instead. You need to escape an extra comma sign.

plugins.security.nodes_dn:
 - CN=ed-master.ed.com,OU=Ops,O=ed.com\, Inc.,DC=ed.com
 - CN=i1.ed.com,OU=Ops,O=ed.com\, Inc.,DC=ed.com
