When accessing the iDRAC Web-based interface, a security warning is displayed stating that the SSL certificate host name
does not match the iDRAC host name.
iDRAC includes a default iDRAC server certificate to ensure network security while accessing through the Web-based interface and
remote RACADM. When this certificate is used, the Web browser displays a security warning because the default certificate that is
issued to iDRAC does not match the iDRAC host name (for example, the IP address).
To resolve this, upload an iDRAC server certificate issued to the IP address or the iDRAC host name. When generating the CSR
(used for issuing the certificate), make sure that the common name (CN) of the CSR matches the iDRAC IP address (if certificate
issued to IP) or the registered DNS iDRAC name (if certificate is issued to iDRAC registered name).
To make sure that the CSR matches the registered DNS iDRAC name:
1.
In iDRAC Web interface, go to
Overview
→
iDRAC Settings
→
Network
. The
Network
page is displayed.
2.
In the
Common Settings
section:
•
Select the
Register iDRAC on DNS
option.
•
In the
DNS iDRAC Name
field, enter the iDRAC name.
3.

Active Directory
Active Directory login failed. How to resolve this?
To diagnose the problem, on the
Active Directory Configuration and Management
page, click
Test Settings
. Review the test
results and fix the problem. Change the configuration and run the test until the test user passes the authorization step.
In general, check the following:
•
While logging in, make sure that you use the correct user domain name and not the NetBIOS name. If you have a local iDRAC
user account, log into iDRAC using the local credentials. After logging in, make sure that:
– The
Active Directory Enabled
option is selected on the
Active Directory Configuration and Management
page.
– The DNS setting is correct on the
iDRAC Networking configuration
page.
– The correct Active Directory root CA certificate is uploaded to iDRAC if certificate validation was enabled.
– The iDRAC name and iDRAC Domain name matches the Active Directory environment configuration if you are using
extended schema.
– The Group Name and Group Domain Name matches the Active Directory configuration if you are using standard schema.
– If the user and the iDRAC object is in different domain, then do not select the
User Domain from Login
option. Instead
select
Specify a Domain
option and enter the domain name where the iDRAC object resides.
•
Check the domain controller SSL certificates to make sure that the iDRAC time is within the valid period of the certificate.
Active Directory login fails even if certificate validation is enabled. The test results display the following error message. Why
does this occur and how to resolve this?
ERROR: Can't contact LDAP server, error:14090086:SSL
routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed: Please check the correct
Certificate Authority (CA) certificate has been uploaded to iDRAC. Please also check if the
iDRAC date is within the valid period of the certificates and if the Domain Controller
Address configured in iDRAC matches the subject of the Directory Server Certificate.
If certificate validation is enabled, when iDRAC establishes the SSL connection with the directory server, iDRAC uses the uploaded
CA certificate to verify the directory server certificate. The most common reasons for failing certification validation are:
•
iDRAC date is not within the validity period of the server certificate or CA certificate. Check the iDRAC time and the validity
period of your certificate.
