Cause
Pro integraci LDAP se službou Active Directory systém vyžaduje certifikát LDAP s FDQN.

Upozorňujeme, že protokol LDAP služby AD není v DDMC podporován.
Resolution
- Zákazník vygeneruje nový certifikát LDAP pomocí FDQN.
- Nainstalujte nový certifikát s FDQN a povolte protokol LDAP.
Příklad:
Certifikát LDPA s FDQN
Certifikát LDPA s FDQN

Additional Information
Níže jsou uvedeny požadavky na dokončení konfigurace protokolu LDAP pomocí služby AD pro uživatele a skupiny.
- Nakonfigurujte skupinu pro uživatele Data Domain ve službě AD a nastavte pro ni GID.
- Každý uživatel služby AD musí mít nastaveno UID a GID.
Příklad:
V DD:
# authentication ldap groups show
LDAP Group Role ---------- ----- myadmins admin ---------- -----
Na serveru AD:
# get-adgroup myadmins -properties * |findstr gidNumber gidNumber : 200 # get-aduser test -properties * |findstr uidNumber uidNumber : 600 #get-aduser test -properties * |findstr gidNumber gidNumber : 200
