Database manager authentication (AUTHENTICATION) = SERVER
Cataloging allowed without authority (CATALOG_NOAUTH) = NO
Trusted client authentication (TRUST_CLNTAUTH) = CLIENT
Bypass federated authentication (FED_NOAUTH) = NOIf I change AUTHENTICATION dbm cfg to CLIENT, connect to SCM without user/pwd is successful.
From the manual:
"If authentication is SERVER, the user ID and password are sent from the client to the server so that authentication can take place on the server....
A value of CLIENT indicates that all authentication takes place at the client. No authentication needs to be performed at the server."
In my example, client and server is the same AIX box. Could you please explain why I need to provide user/pwd when connecting to a db that is catalogued as remote but pointing to local?
