Map LDAP groups to CelerData cluster
This topic describes how to map the user and group membership information in your LDAP service to your CelerData cluster. By allowing access of your LDAP information to your CelerData cluster, you enable the cluster to automatically manage the users and privileges according to your LDAP information, not only greatly simplifying the authentication and authorization experiences with LDAP on your CelerData cluster, but also significantly increasing the consistency of user information between the two services.
Privileges
Privileges granted to a user or role determine which operations the user or role can perform on certain objects. Privileges can be used to implement fine-grained access control to safeguard data security.
