How to set up fingerprint using Wyse Device Manager

1. Export the WDM server certificate from the WDM server that you want to access.
2. Extract the fingerprint value from the WDM certificate in the required format.
   You must use a system with OpenSSL installed. OpenSSL can be used to extract the fingerprint in required format from the WDM certificate itself.
   The fingerprint is generated from the following command:

   openssl x509 -in <your certificate name>.crt -pubkey -noout | openssl pkey -pubin -outform der | openssl dgst -sha256 -binary | openssl enc -base64

   NOTE: If cert.crt is in DER format instead of the PEM format, you must add -inform to the first command. The certificate supports SHA256 in base64 encoded format.
3. Configure either the DHCP option or the DNS TXT record.
   • If you want to use the DHCP option, configure the following option tags defined in the DHCP server:
     • Option ID—200
     • Name—WDM_Fingerprint
     • Type—String
   • If you want to use the DNS TXT record, enter the name as WDM_Fingerprint, and provide the fingerprint string value.
