NOTE: Any configuration attributes not directly supported by the Server Manager graphic interface may be added as a check item under the Free tab on the User Creation screen.
Authentication-Type:

The authentication type is applied to a user just as it would be applied to a user belonging to a realm. Check and reply items in the user entry will be appended to any items used later in the authentication process.

Comment:

This attribute does not perform any server function. It allows you to provide any necessary explanation for the entry.

Deny-Message:

This attribute specifies a string that would be returned as a Reply-Message value to the user in the Access-Reject if any deny item for this user caused a rejection. You may configure a denial message as follows:

Deny-Message = "You can't do that."
NAS-Port != 3160

(under the Free tab in the Check Item list box)

You may also use an asterisk wildcard:

Deny-Message = "*"
NAS-Port != 3160

This wildcard string sends the following message indicating what deny item triggered the rejection:

Access denied, NAS-Port != 3160 

IMPORTANT: The Deny-Message will only be returned if a deny item (Attribute != Value) comparison fails. It will not be returned if a check item fails.
Expiration:

In date format, specifies when an entry expires. After the date, the user will receive an Access-Reject with the message, "Password has expired," in response to all Access-Requests. The correct syntax is as follows:

Expiration = mth day year

mth is the first three letters of the month. day is the two-digit date. year is the four-digit year. The following is an example of an Expiration check item:

Expiration = Jan 31 2004

Group-Name:

May be any string value. Unlike other configuration-only attributes, Group-Name would initially appear in a user entry as a reply item and would be used as a check item in a policy definition by ProLDAP or a customized authentication method.

Password:

Specifies the value to compare to the User-Password attribute value in the Access-Request or the user's input in response to an Access-Challenge. The \ character may not be used.

NOTE: The RADIUS protocol does not send clear text passwords. Passwords are encrypted with the client and server's shared secret according to RFC 2865.

To specify an encrypted password you must follow the syntax {Encrypt-type}Encryptd-password, where Encrypt-type is the method used to encrypt the password and Encryptd-password is the encrypted password. Encrypt-type can be specified as:

  • crypt

  • md5

  • x-nthash

  • x-lmhash

Server-Name:

The additional parameter, usually a DNS name or IP address, required to perform the specified authentication type.

User-Category:

May be any string value. Unlike other configuration-only attributes, User-Category would initially appear in a user entry as a reply item and would be used as a check item in a policy definition by ProLDAP or a customized authentication method.

Xvalue:

This attribute provides a means to pass an integer value to an action.

Xstring:

This attribute provides a means to pass a string value to an action.

LAS Configuration

Some configuration-only attributes define information for authorization through the servers local authorization service (LAS). To activate the features related to these attributes for users in a given realm, you must enable session tracking for the user's realm. A NULL realm entry will still be required if the user does not belong to a realm. The following attributes may be used in a user entry for LAS functions:

Simultaneous-Use:

This attribute's value determines the maximum number of active sessions the user may have. 1 is the default (if the LAS is enabled for the user's realm, but no Simultaneous-Use attribute value is specified for the user or the user's realm). A value of -1 will disable the feature—providing no limit to number of simultaneous sessions for a user in a realm enabled to use the LAS.

Session-Limit:

An alias for Simultaneous-Use. You can use either attribute to limit the number of active sessions.
