Network security
While accessing the iDRAC Web interface, a security warning appears stating that the SSL certificate
issued by the Certificate Authority (CA) is not trusted.
iDRAC includes a default iDRAC server certificate to ensure network security while accessing through the
Web-based interface and remote RACADM. This certificate is not issued by a trusted CA. To resolve this,
upload a iDRAC server certificate issued by a trusted CA (for example, Microsoft Certificate Authority,
Thawte or Verisign).
Why the DNS server not registering iDRAC?
Some DNS servers register iDRAC names that contain only up to 31 characters.
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. Click Apply.

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:
