Authentication
If you are using LDAP or Microsoft Active Directory with 
TLS
, you need to download a CA list to 
the IOLAN that includes the certificate authority (CA) that signed the LDAP certificate on the LDAP 
host by selecting 
Tools
Advanced
,
 Keys and Certificates
. See 
 for more 
information on the LDAP certificate.
User Attribute
This defines the name of the attribute used to communicate the user name to 
the server.
Options:
z
OpenLDAP(uid)—Chose this option if you are using an OpenLDAP 
server. The user attribute on this server is “uid”.
z
Microsoft Active Directory(sAMAccountName)—Chose this option if 
your LDAP server is a Microsoft Active Directory server. The user 
attribute on this server is “sAMAccountName”.
z
Other—If you are running something other than a OpenLDAP or 
Microsoft Active Directory server, you will have to find out from your 
system administrator what the user attribute is and enter it in this field.
Default: OpenLDAP(uid)
Encrypt Passwords 
Using MD5 digest
Checking this parameter will cause the IOLAN to encrypt the password using 
MD5 digest before sending it to server. If this option is not checked, the 
password is sent to the server in the clear.
Default: Disabled
Authenticate 
IOLAN with LDAP 
server
This option will cause the Terminal Server to authenticate with the LDAP 
server before the user authentication takes place. The user name/password to 
use for this authentication is configured below.
Default: Disabled
Name
The user name associated with the IOLAN
Append Base to 
Name
When checked, this causes the domain component configured in the “base” 
parameter to be appended to the user name. This allows for a fully qualified 
name to be used when authenticating the IOLAN.
Default: Enabled but if the base parameter is not configured, it does not 
modify the name.
Confirm
You must enter the exact same value as the password field. Since the password 
is not echoed, this ensures that the field was entered correctly.
Default: Blank
Enable TLS
Enables/disables the Transport Layer Security (TLS) with the LDAP/Microsoft 
Active Directory host.
Default: Disabled.
TLS Port
Specify the port number that LDAP/Microsoft Active Directory will use for 
TLS
Default: 636
