arriving in the morning, then you could ask them to type a PIN code in the first time they are outcalling someone.

Do you store devices passwords (BIOS passwords with Serial numbers, ...) in an LDAP database ? <br><br>If it describes users, then obviously you would like to use the same tools as for other IT applications with LDAP databases and so on.<br><br>From my point of view, a good comparison would be to treat IP phones just like PCs : if you ask user to type a password to gain network access when arriving in the morning, then you could ask them to type a PIN code in the first time they are outcalling someone. <br><br>Regards<br><br> ------=_Part_18384_10937620.1195993845761--
