The GET_ALL_USERS command will return all USER_LOGIN parameters in the user database. For this command to parse correctly, the command must appear within a USER_INFO command block, and USER_INFO MODE can be in read or write. The user must have the administrative privilege to retrieve all user accounts.
Example:
<RIBCL VERSION="2.0">
<LOGIN USER_LOGIN="adminname" PASSWORD="password">
<USER_INFO MODE="read">
<GET_ALL_USERS />
</USER_INFO>
</LOGIN>
</RIBCL>
