First you must choose a profile to work with. If none is available the host admin must define some using the profile setup dialog.
Enter the search value in the "Entry field". Normally this will be an accountname or a name. You may use wildcards. A wildcard only (*) will return a list of all entries in this directory.
The formclient will connect to the directory using the curent binding and update an entry. If the entry is missing or the binding does not have write access, the update will fail.
The formclient will add an empty entry to the directory constructed from the value in the "Entry Key" field. You have to use modify after adding an entry to update with more data.
This will delete the current entry, if the binding allows it.
