Specifies SQL query that will be used to store Yubikey token
data back to the database after authentication. Special characters are
permitted, and %0 is replaced with the new session counter, %1 with the
new session_use counter, %2 with 0 (this column not currently used), %3
with the quoted user name, %4 with the quoted token ID in Base64, %5 with
the current time (seconds in the unix epoch), %6 with the token ID in Hex
and %7 with the token ID in modhex. The default works with the sample
Yubikey database created by db_schema.sql from the YubiKey Validation
Server. The default is:
UpdateQuery update yubikeys set accessed=current_timestamp(),
counter=%0, low=%1, high=%2 where userId=%3
which assumes that
there is a one-to-one mapping between Yubikeys and users. You could
support multiple tokens per user or multiple user per token with a custom
Update- Query like:
UpdateQuery update yubikeys set accessed=current_timestamp(),
counter=%0, low=%1, high=%2 where tokenId=%4 and userId=%3
