Dell Unity: Il comando Uemcli ha avuto esito negativo con "Impossibile convalidare il certificato specificato" dopo l'aggiornamento alla versione 5.5 (correggibile dal cliente)

• Uemcli comandi in esecuzione sulla CLI di Unity OE 5.5 non riusciti con errore "Unable to validate the specified certificate. (Error Code:0x1000100)". 

13:23:45 service@emcunity02-2 spa:~/user# uemcli /sys/general show
Storage system address: 127.0.0.1
Storage system port: 443
HTTPS connection

Operation failed. Error code: 0x1000100
Unable to validate the specified certificate. (Error Code:0x1000100)

• Gli stessi comandi non hanno esito negativo quando vengono eseguiti da client Windows e client Linux con la versione più recente di Uemcli installata o Unity OE precedente alla versione 5.5. 
• Il problema si verifica solo sui sistemi Unity con certificato firmato dalla CA immutato. 
• Anche il controllo integrità precedente all'aggiornamento avrà esito negativo poiché lo script esegue più uemcli .

• La catena di certificati che il cliente ha importato in Unity può contenere o meno il certificato CA radice. Il problema si verifica solo su Unity quando la catena di certificati importata contiene il certificato CA radice. 
• La soluzione alternativa è disponibile, ma la root cause è ancora in fase di analisi. L'articolo della KB verrà aggiornato quando sarà disponibile la root cause. 
• Esistono 2 metodi per verificare se la catena di certificati importata contiene il certificato CA radice. 

Metodo 1. 

Utilizzare openssl s_client -connect <Unity mgmt ip:443> -showcerts per elencare la catena di certificati.

Il certificato CA radice è un certificato autofirmato e ha sempre lo stesso oggetto e lo stesso autorità di certificazione. 

 2 s:DC = lab, DC = peeps, CN = peeps-PEEPS-DC-CA   <<<<<<
   i:DC = lab, DC = peeps, CN = peeps-PEEPS-DC-CA   <<<<<<

Metodo 2.

Eseguire openssl x509 in <certificate file> -text -noout | grep -E "Issuer:|Subject:" nel file di certificato per elencare i certificati. 

00:50:09 root@VIRT2213Y2XXXX spa:/cores/service/user# openssl x509 -in unity_pod1.pem -text -noout | grep -E "Issuer:|Subject:"
        Issuer: DC = lab, DC = peeps, CN = peeps-WIN2022-CA
        Subject: C = IE, ST = Cork, L = Ovens, O = DellEMC, CN = peeps-pod1-unityvsa.peeps.lab

Soluzione alternativa:

• Seguire KB000021122 per importare una nuova catena di certificati che non include il certificato CA radice in Unity. 

Nota: 

• Se il certificato Unity è firmato dalla CA radice, il certificato importato in Unity deve essere un singolo certificato che è il certificato Unity stesso.  
• Se il certificato Unity è firmato da una CA intermedia, la catena di certificati deve essere configurata come una sequenza completa e ordinata. Questa catena deve includere:

1. Il certificato del server Unity (certificato dell'entità finale),

2. Tutti i certificati CA intermedi nel percorso gerarchico,

3. Escluso il certificato CA radice, che deve già esistere nel truststore del client.

La catena deve essere ordinata dal certificato dell'entità finale fino all'emittente immediato, assicurando che i client possano tracciare un percorso di attendibilità a una CA radice pre-attendibile. Ad esempio:

Unity Certificate → Intermediate CA 2 → Intermediate CA 1
