TPM_20_E_AUTH_CONTEXT
TPM_20_E_AUTH_CONTEXT maps to TPM_RC_AUTH_CONTEXT. An authorization session was attached to a context command or another command that cannot accept authorization sessions. The session might be valid in general, but it is invalid for this command form.
How to correct the request
- Read the command’s required tag and authorization index in the TPM command definition.
- Build a no-session command when the command definition requires
TPM_ST_NO_SESSIONS. - Do not replace this with a different credential; the error is about command eligibility for sessions, not authorization strength.
