The problem is those databases subscribed by only one or partial libraries. For example, db 1 was subscribed by only library a, but in library b, a user can go to library a's page and click the link.

Yi,

As was mentioned, you may have to go the multiple-IP route (#105455), but you may be able to get away with just using the HOME column in the forward table ( http://csdirect.iii.com/faq/wam.shtml#homfld ) provided that:

1) you force verification on the affected databases
2) databases that are affected are not part of aggregator collections that multiple libraries have different databases from, unless those databases have distinct elements to their URLs.

Granted, that can be very limiting and you may have to go for the multiple-IP route, but for many small consortiums, this can be the less expensive route. Also, the HOME column can be used in conjunction with the multiple-IP route to really limit use of specific databases to patrons from specific campuses even when they are visiting a different campus...

Let's say we have three libraries: Lib1, Lib2 and Lib3. Lets say they have the following subscriptions:

1)
Only Lib1 subscribes to database A from Vendor Z and the URL is like
www.vendorZ.com/dbA

2)
Only Lib2 subscribes to database B from Vendor Z and the URL is like:
www.vendorZ.com/dbB

3)
Only Lib1 also subscribes to database C from Vendor Y and the URL is like:
www.vendorY.com

4)
Both Lib1 and Lib2 subscribe to database D from Vendor X and the URL is like:
www.vendorX.com

As long as the "db*" part of the URL is always present in #1 and #2, these entries will work:

1 > Token                  dbA
2 > IP Address/Host Name   *.vendorZ.com
3 > Port                   80
4 > Service Level          0
5 > Verify                 Y
6 > Valid Patron Types     0-255
7 > Valid Patron Home Libs   Lib1
8 > Database Identifier    dbA
9 > Database Name          DBA from Vendor Z

1 > Token                  dbB
2 > IP Address/Host Name   *.vendorZ.com
3 > Port                   80
4 > Service Level          0
5 > Verify                 Y
6 > Valid Patron Types     0-255
7 > Valid Patron Home Libs   Lib2
8 > Database Identifier    dbB
9 > Database Name          DBB from Vendor Z

1 > Token                  dbC
2 > IP Address/Host Name   *.vendorY.com
3 > Port                   80
4 > Service Level          0
5 > Verify                 Y
6 > Valid Patron Types     0-255
7 > Valid Patron Home Libs   Lib1
8 > Database Identifier    dbC
9 > Database Name          DBC from Vendor Y

1 > Token                  dbD
2 > IP Address/Host Name   *.vendorX.com
3 > Port                   80
4 > Service Level          0
5 > Verify                 Y
6 > Valid Patron Types     0-255
7 > Valid Patron Home Libs   Lib1,Lib2
8 > Database Identifier    dbD
9 > Database Name          DBD from Vendor X
