User authentication

LDAP user configuration

When configured to use LDAP support, the IX10 device uses a remote LDAP server for user
authentication (password verification) and authorization (assigning the access level of the user).
Additional LDAP servers can be configured as backup servers for user authentication.
This section outlines how to configure a LDAP server to be used for user authentication on your IX10
device.
There are several different implementations of LDAP, including Microsoft Active Directory. This section
uses OpenLDAP as an example configuration. Other implementations of LDAP will have different
configuration methods.
Example OpenLDAP configuration
With OpenLDAP, users can be configured in a text file using the LDAP Data Interchange Format (LDIF).
In this case, we will be using a file called add_user.ldif.
1. Create the add_user.ldif file in a text editor. For example:
$ gedit ./add_user.ldif
2. Add users to the file using the following format:
dn: uid=john,dc=example,dc=com
objectClass: inetOrgPerson
cn: John Smith
sn: Smith
uid: john
userPassword: password
ou: admin serial
The value of uid and userPassword must correspond to the username and password
n
used to log into the IX10 device.
The ou attribute is optional. If used, the value must correspond to authentication
n
groups configured on your IX10. Alternatively, if the user is also configured as a local
user on the IX10 device and the LDAP server authenticates the user but does not return
any groups, the local configuration determines the list of groups. See
groups
Other attributes may be required by the user's objectClass. Any objectClass may be used as
long it allows the uid, userPassword, and ou attributes.
3. Save and close the file.
4. Add the user to the OpenLDAP server:
$ ldapadd -x -H 'ldap:///' -D 'cn=admin,dc=example,dc=com' -W -f add_
user.ldif
adding new entry "uid=john,dc=example,dc=com"
5. Verify that the user has been added by performing an LDAP search:
$ ldapsearch -x -LLL -H 'ldap:///' -b 'dc=example,dc=com'
uid=john
dn: uid=john,dc=example,dc=com
objectClass: inetOrgPerson
