[GeoNode-users] LDAP configuration and troubleshooting in SPCGeonode

[Alessio Fabiani]

Dear Chiara,
typically the issue is mostly related to misconfiguration. You'll need to
be sure the following parameters have been correctly configured and the
filters actually return the entities you are looking for

LDAP_SERVER_URL=ldap://<the_ldap_server>
LDAP_BIND_DN=uid=ldapinfo,cn=users,dc=ad,dc=example,dc=org
LDAP_BIND_PASSWORD=<something_secret>
LDAP_USER_SEARCH_DN=dc=ad,dc=example,dc=org
LDAP_USER_SEARCH_FILTERSTR=(&(uid=%(user)s)(objectClass=person))
LDAP_GROUP_SEARCH_DN=cn=groups,dc=ad,dc=example,dc=org
LDAP_GROUP_SEARCH_FILTERSTR=(|(cn=abt1)(cn=abt2)(cn=abt3)(cn=abt4)(cn=abt5)(cn=abt6))
LDAP_GROUP_PROFILE_MEMBER_ATTR=uniqueMember

Unfortunately, there's no standard configuration here. This really depends
on your LDAP structure.

It is worth trying the filters first from the Django shell, as an instance:

import ldap
conn = ldap.initialize("ldap:// <the_ldap_server> ")
conn.simple_bind_s("<LDAP_BIND_USER_FULL_DN>", "<LDAP_BIND_PASSWORD>")

# Search users
conn.search_s("ou=something,dc=ad,dc=example,dc=org", ldap.SCOPE_SUBTREE,
"(&(uid=*)(objectClass=person))")

# Search groups
conn.search_s("cn=groups,dc=ad, dc=example,dc=org", ldap.SCOPE_SUBTREE,
"(|(cn=group1_name)(cn=group2_name)(cn= group2_name
)(cn=group3_name)(cn=group4_name)(cn=group5_name))")

Once you are sure your filters return what you need (users and groups) you
can put those into the settings.

If everything works as expected, at first login, if the user does not
exist, GeoNode will try to authenticate against your LDAP server. If
successful, it will get user info from LDAP and will create the internal
user accordingly.

In order to keep Groups and Users synchronized with LDAP, you will need to
create some cron jobs running every X minutes, checking for changes on the
LDAP tree.

Regards,
Alessio.
