With LDAP (Lightweight Directory Access Protocol) support, you no longer need to enter the recipient's entire e-mail address on the AR-M450's/M350's control panel. Just press the GLOBAL ADDRESS SEARCH button and enter the search name using the keyboard shown on the LCD touch panel. This immediately brings up a matching list of possible recipients. LDAP simplifies this process - just select the name and press "send."
 Detected Address List
Compatible with high-security authentication methods such as DIGEST-MD5 and Kerberos, the AR-M450/M350 keeps your sensitive documents away from prying eyes. Select from the following 5 authentication methods:
 | Anonymous: Connect without entering a user name or password; |
 | Simple: Connect after authenticating your user name and password in plain text; |

 | Digest-MD5*2: Connect after authenticating your user name and password converted to Digest-MD5; |

 | NTLM*2: Connect after authenticating your user name and password by NTLM; |

 | Kerberos*2: Connect after obtaining an access ticket from a KDC server using your user name and password. (Note: Settings must be made separately on the KDC server.) |
| *1 | | Both AR-NS2 and AR-FX5 are required. |
| *2 | | This authentication method will be available at a later date. |
| **1 | | When the Data Security Kit is installed, this function cannot be used. |
