Appendix C. Manually Configuring Integration with Novell eDirectory
Repeat the steps above for the uidNumber and gidNumber attributes, adjusting parameters as needed.
C.3. Removing Attribute Mappings
After extending the schema, two attribute mappings must be removed for proper operations. If they are
not removed, neither uidNumber nor gidNumber will work as needed.
Attribute mappings are used to map LDAP attribute names to NDS attribute names as a compatibility
feature of Novell NDS. Since NDS has been around for a longer time than the LDAP specification, a lot
of software exists that use the NDS names of object classes and attributes.
In order for LDAP authentication to work, the mapping from uidNumber to UID as well as the one from
gidNumber to GID must be removed.
To remove the mappings you right click on the LDAP group entry at root level of your tree and select
Properties . Under the Attribute map tab is a list of attribute mappings. Depending on your version of
eDirectory and your version of Console One, there are either direct mappings between gidNumber and
GID, or a mapping between groupID and GID, with gidNumber as a secondary LDAP attribute. If there
is a search function available, use that to locate the relevant mappings, and delete them.
One symptom of the fact that attribute mappings for gidNumber and uidNumber have not been removed
is that when searching eDirectory for groups without specifying what attribute to fetch, the gidNumber
shows up, but when explicitly specifying that gidNumber should be fetched, no data is returned.
C.4. Adding nss_map_attribute statements to /etc/ldap.conf
For NSS (looking up information about users and groups) to work well when fetching information from
eDirectory, the following three lines should be in /etc/ldap.conf
nss_map_attribute uniqueMember member
nss_map_attribute uid cn
pam_password nds
The first two make sure that the Linux machine asks for the correct attributes, and more importantly, that
when processing a request to find out which groups a user is member of, it doesn’t have to lookup every
DN found as a member to find out which uid it corresponds to. The last line makes sure changing
passwords in eDirectory from Linux works. Use any PAM-enabled password-changing program in Linux
to achieve this functionality.
C.5. Creating a DN for search operations
In most environments, it’s not a good idea to setup eDirectory so that anyone can read the attributes
needed by LDAP Authentication (uid, uidNumber, gidNumber, homeDirectory and loginShell).
Depending on the network setup, the information may be more or less sensitive. To prevent this, a special
user is created in the database, and all search operations from the ThinLinc servers are made after
binding as this user. This way, the amount of information that can be extracted by an anonymous user is
limited. However, all users on the ThinLinc servers can read the password of this user, so the protection
is limited. The user must have access to the mentioned attributes. In this section, we will describe how to
create this user and setup the access control.
