Remote Operations

Each DSA has a context prefix that defines the base of the DIT controlled by that DSA.

When the DSA receives an incoming operation, it services the request locally when it is in the DSA's own section of the namespace. When the operation is not local, it chains the operation to a remote DSA except in the following circumstances:

• One (user) service control (either chainingProhibited or localScope) is set.
• The remote DSA is unavailable.
• You cannot establish a link of the appropriate authentication level to the remote DSA.
• There is no DSA knowledge for the area of the operation.

Depending on the circumstance, the remote operation returns one of the following options:

• Result
• Referral
• Service error
• Security error

See the X.500 standards for a complete specification of how distributed DSAs cooperate to resolve a query.
