Re: ILO login issue with Active directory credential

Have you checked by Importing an LDAP CA Certificate (Page number 459 - 261)

Please refer HPE iLO 5 2.10 User Guide for Setting up management processors for directories (Page number 459 to 461 )

Re: ILO login issue with Active directory credential

Hi AmRa,

thanks for your reply, we are not not looking here to implement custom Certificate for each servers ILO, hope the AD integration will work event without implementing custom certificate and it is working fine most of the servers.

as informed we have not applied any custom certificate and not sure why we are getting "LDAP server certificate validation failed" error, also not sure why the same AD authentication working after ILO reset.

Re: ILO login issue with Active directory credential

We have seen similar issue has been fixed by re-generate a CSR certificate or restore iLo to factory default settings and re-configuring iLO.

Re: ILO login issue with Active directory credential

as informed we cannot regenerate CSR since we have not applied the custom certificate, also we have more than 5000 physical server and we cannot keep on reseting the ILO or reconfigure it,

looking for the cause &  permennet fix.

For iLO 3 and iLO 4 we found below customer advisory, however for iLO5 there is no HPE knowledge base article available for reported issue. Hence please raise support ticket with HPE support team for further troubleshooting.

Re: ILO login issue with Active directory credential

Hi AmRa,

seems the KB is not relevent for us, since the user is part of only one group (not in more than 300 group). let us raise support case & work on this issue.

Thanks for your support again.
