I would like to know if it is possible or if there is any tool to be able to massively set the "accountSetting" and "preferredLanguage" attributes to all the users that I have! I looked for a way to do it in phpLDPadmin and I couldn't, it only lets me do it one by one, and by command line directly in ldap I can't do it.

Could you help me with this. Thanks in advance.
