You can restrict the synchronization of LDAP directory groups when using the Hue useradmin application by setting a base filter (group_filter attribute) and the username attribute in the LDAP schema (group_name_attr attribute) of the /etc/hue/conf/hue.ini file:

[[[groups]]]

# Base filter for searching for groups
group_filter="objectclass=*"

# The username attribute in the LDAP schema
group_name_attr=cn
