docs(jdisc-connector): document the Active Directory user and user group import

[MichaelOv]

The JDisc Connector can import Active Directory users and user groups as person and person group objects. This documents the two new sync profile options and the organizational unit filter on the JDisc Connector page, in English and German.

What is documented

• Three new rows in the General table of the sync profile section, with a link into the new section.
• New section Active Directory users and user groups covering:
  • the prerequisite in JDisc Discovery (DNS domain controller with credentials, user discovery on the Data Collection tab, directory scope set to subtree, the synchronize users and user groups options of the discovery job),
  • the three options as a table,
  • where group memberships end up and how members of nested groups are handled,
  • a note that persons are matched by their LDAP DN, so instances that already run ldap-sync get no duplicates, and that nothing is overwritten, archived or deleted.

Screenshots

Two per language, 1920x1080: the sync profile options with the organizational unit filter, and the resulting Person group members category.
