User authentication
LDAP user configuration
When configured to use LDAP support, the Connect IT Mini 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
Connect IT Mini 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 Connect IT Mini device.
The ou attribute is optional. If used, the value must correspond to authentication
n
groups configured on your Connect IT Mini. Alternatively, if the user is also configured as
a local user on the Connect IT Mini device and the LDAP server authenticates the user
but does not return any groups, the local configuration determines the list of groups.
See
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
cn: John Smith
