Using LDAP or LDAP+GSSAPI

LDAP is a standards

‑

based, cross

‑

platform, extensible protocol that runs directly on top of the TCP/IP layer. It

is used to access information stored in a specially organized information directory. It can interact with many

different kinds of databases without special integration, making it more flexible than other authentication

methods.

LDAP+GSSAPI is used when you want your transmission to be always secure. Instead of authenticating directly

with the LDAP server, the user is first authenticated with a Kerberos to obtain a Kerberos ticket. This ticket is

presented to the LDAP server using the GSSAPI protocol for access. LDAP+GSSAPI is typically used for networks

running Active Directory.

Notes:

•

LDAP+GSSAPI requires a Kerberos network account. For more information, see

“Creating a Kerberos

login method” on page

19

.

•

Supported printers can store a maximum of five unique LDAP or LDAP+GSSAPI login methods. Each

method must have a unique name.

•

Administrators can create up to 32 user

‑

defined groups that apply to each unique login method.

•

LDAP and LDAP+GSSAPI relies on an external server for authentication. If the server is down, then users

are not able to access the printer using LDAP or LDAP+GSSAPI.

•

To help prevent unauthorized access, log out from the printer after each session.
