Cause

Per l'integrazione LDAP con Active Directory, il sistema richiede un certificato LDAP con FDQN.

sysadmin@dd01# adminaccess certificate show
Subject               Type          Application   Valid From                 Valid Until                Fingerprint
-------------------   -----------   -----------   ------------------------   ------------------------   -----------------------------------------------------------
dd01.lab.example.com   host          https         Sat Aug 15 09:14:31 2020   Tue Aug 15 16:14:31 2023   D3:B6:F8:B6:3C:91:DA:B8:BB:96:44:38:3F:85:10:BD:A9:23:9E:D9
lab-MYADSERV-CA        imported-ca   ldap          Mon Aug 16 21:51:24 2021   Sun Aug 16 22:01:23 2026   B7:40:A1:FA:7D:19:B6:D0:EB:FF:5D:72:70:64:43:E1:6B:70:5E:75
-------------------   -----------   -----------   ------------------------   ------------------------   -----------------------------------------------------------

Tenere presente che AD LDAP non è supportato su DDMC.

Resolution

  1. Il cliente deve generare un nuovo certificato LDAP con FDQN.
  2. Installare il nuovo certificato con FDQN e abilitare LDAP.
Esempio:
Certificato LDPA con FDQN  
sysadmin@dd01# adminaccess certificate show

Additional Information

Di seguito sono riportati i requisiti per completare la configurazione LDAP utilizzando AD per utenti e gruppi.
  1. Configurare un gruppo per gli utenti Data Domain in AD e impostare il GID per tale gruppo.
  2. Ogni utente AD deve avere l'UID e il GID impostati.
Esempio: 
Su DD: 
# authentication ldap groups show
LDAP Group   Role
----------   -----
myadmins     admin
----------   -----
Sul server 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
