Cascaded NABs
For Domino versions prior to 4.6.1, you can use cascaded Address Books. In Domino 4.6.2, modifications and enhancements in the way name lookups are performed from the Web mean that only the primary NAB is used for Web authentication. Therefore, in Domino 4.6.2 you must use a Master Address Book for authentication with multiple Address Books. However, due to customers' requests, a NOTES.INI variable was introduced in 4.6.2a that allows the use of cascaded Address Books, instead of the MAB, for Domino 4.6.2a and later. To use cascaded Address Books in 4.6.2a or later, add the following setting to the server's NOTES.INI:
NoMABForWebNames=1
In R5, Web clients cannot authenticate from cascaded Public Address Books or Domino Directories (the NAMES= line in the NOTES.INI file). To authenticate Web clients using secondary address books or directories in R5, set up Directory Assistance.
Valid Values are:
0: don't use cascaded Address Books
1: use cascaded Address Books
