I am trying to find a way from the command line to search for a users exchange email address based on the user name. This exposed my lack of understanding for 'net ads search' The man page for 'net' in the search section says "Perform a raw LDAP search on a ADS server and dump the results. The expression is a standard LDAP search expression, and the attributes are a list of LDAP fields to show in the results." So I tried net --user=myuser ads search '(objectClass=user)(email=*)' which errors: search failed: Bad search filter Can someone offer some advice on: a) why is that a bad ldap search filter? b) what search would get the exchange email address for a given users?
