When AdminP processes a password change in Lotus Notes/Lotus Domino, the old password is cached by the server for two days. What if this cache period is too long or too short ? Can the cache period ever be modified?
Yes, the cache period can be modified by setting the following parameter in the server's notes.ini file:
Use the following format:
(where x is the number of hours of caching time for the old password)
During the cache period, both old and new passwords are valid, assuming the change has replicated to the server being accessed.
In addition, the Security Settings Document --> Password Management --> "Allow users to change Internet password over HTTP" field must be set to Yes.
