Dell iDRAC8 manual

–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.

•The domain controller addresses configured in iDRAC does not match the Subject or Subject Alternative Name of the directory server certificate. If you are using an IP address, read the next question. If you are using FQDN, make sure you are using the FQDN of the domain controller and not the domain. For example, servername.example.com instead of example.com.

Certificate validation fails even if IP address is used as the domain controller address. How to resolve this?

Check the Subject or Subject Alternative Name field of your domain controller certificate. Normally, Active Directory uses the host name and not the IP address of the domain controller in the Subject or Subject Alternative Name field of the domain controller certificate. To resolve this, do any of the following:

•Configure the host name (FQDN) of the domain controller as the domain controller address(es) on iDRAC to match the Subject or Subject Alternative Name of the server certificate.

•Reissue the server certificate to use an IP address in the Subject or Subject Alternative Name field, so that it matches the IP address configured in iDRAC.

•Disable certificate validation if you choose to trust this domain controller without certificate validation during the SSL handshake.

How to configure the domain controller address(es) when using extended schema in a multiple domain environment?

This must be the host name (FQDN) or the IP address of the domain controller(s) that serves the domain in which the iDRAC object resides.

When to configure Global Catalog Address(es)?

If you are using standard schema and the users and role groups are from different domains, Global Catalog Address(es) are required. In this case, you can use only Universal Group.
