Sample NDS_BACKLINKS
Before eDirectory checks any backlinks or external references, it queries WAN Traffic Manager to
see if this is an acceptable time for this activity. NDS_BACKLINKS does not have a destination
address; it requires a NO_ADDRESSES policy. If WAN Traffic Manager returns DONT_SEND,
backlink checking will be put off and rescheduled. The following variables are supplied:
Š Last (Input Only, Type TIME)
The time of the last round of backlink checking since eDirectory started. When eDirectory
starts,
Last is initialized to 0. If NDS_BACKLINKS returns SEND, Last is set to the current
time after eDirectory finishes backlinking.
Š
Version (Input Only, Type INTEGER)
The version of eDirectory.
Š
ExpirationInterval (Output Only, Type INTEGER)
The expiration interval for all connections created while backlinking.
Š
Next (Output Only, Type TIME)
Tells eDirectory when to schedule the next round of backlink checking.
Š
CheckEachNewOpenConnection (Output Only, Type INTEGER)
Tells eDirectory what to do if it needs to create a new connection while doing backlinking.
CheckEachNewOpenConnection is initialized to 0.
Š CheckEachAlreadyOpenConnection (Output Only, Type INTEGER)
This variable tells eDirectory what to do if it needs to reuse a connection it believes is already
open while doing backlinking. CheckEachAlreadyOpenConnection is initialized to 0.
Value Description
<0, 0 Use the default expiration interval (default).
>0 Expiration interval to be assigned to this connection.
Value Description
In past, 0 Use the default scheduling.
In future Time when backlinking should be scheduled.
Value Description
0 Return Success without calling WAN Traffic Manager, allowing the
connection to proceed normally (default).
1 Call WAN Traffic Manager and let the policies decide whether to allow the
connection.
2 Return ERR_CONNECTION_DENIED without calling WAN Traffic
Manager, causing the connection to fail.
