LDAP Data Interchange Format(LDIF)

Q

How does authorization work in Splunk?

A
  • In order for a user to login they must have a User Account and A ROLE assigned.
  • Cannot assign Access/Capabilities to a user. They must be assigned to Roles.
  • Roles can only Assign Capabilites, Not Remove them.
  • Rest API Data Access Query
    https: //host:port/services/authorization/roles/admin
  • To faithfully restrict access to data it must be in its own index, and restricted from there. Search time obfuscation can be subverted
  • Create separate indexes for data with diffferent classifications, and User access levels
  • Default User Role has access to all Non-Internal indexes

Q

Can Splunk use multiple LDAP servers?

A

Yes, and as soon as Splunk locates a user on the server, it stops searching.

Search order is determined by the Connection order field..

If the user also has credentials on a server later in the search order, those credentials are ignored.
