should be rather easy:

all users:
ldapsearch -x -LLL -b ou=people,$BASEDN uid|grep ^uid|sed 's/^uid:\ //'|sort -u

users that used OX:
# fgrep logout /var/log/openexchange/groupware.log|fgrep -v null|sed 's/^.*-\ //'|sort -u

depending on when your logfiles are rotated you may simply habe to
replace groupware.log with the rotated version for the relevant
timespan (e.g. last month) and fgrep with zfgrep, if logs are
compressed.
otherwise you'd have to either cut off the unneeded parts from a copy
of that logfile or write a small (e.g. perl) snipplet that parses the
date and only spits out lines matching your desired timespan.

if you have them at least seperated by year this could be as simple as
adding
  grep ^Mar
to the filter above (to filter by month, e.g march).
