NTLM authentication fails with the error: RPC exception: Failed to verify checksum of the packet.
User authentication fails.
-- Start nlad process with 'encryption'. -- Configure a user, and map that user to a huge number of groups. -- Configure NTLM front-end authentication.
1. Run the 'nlad' process with '-encrypt no' in the file /etc/bigstart/startup/nlad. 2. Disable encryption for nlad: # vim /etc/bigstart/startup/nlad change: exec /usr/bin/${service} -use-log-tag 01620000 to: exec /usr/bin/${service} -use-log-tag 01620000 -encrypt no 3. Restart nlad to make the change effective, and to force the schannel to be re-established: # bigstart restart nlad
