11.10.3 Password checking events
Here we show the complete set of password checking events, from beginning to
end. Both a pseudocode representation of the process and an associated
flowchart (which conforms in all points to the pseudocode) is provided here.
The warnings detailed previously can be seen in the flowchart and in the
pseudocode. As well, there are some additional checks carried out by the server
to ensure that digests and dates are kept in sync. A good example of this is when
the client sends a user's ID digest to the server that is stamped with a date so far
in advance of the server time that it hints to the server that there must be
something wrong with the client OS clock. In such a situation, the client will see
the following message: "Connection failed because of a problem with clock
synchronization and password change intervals. Check your clock
setting, change your password, or consult your system administrator."
Both the flowchart and the pseudocode also help show in what state the Notes
user ID and person documents are when clients receive warnings or are denied
access to the server.
The flowchart can be found in Figure 11-19 on page 493, while the pseudocode
is listed on the pages immediately after.
