AD Authentication same Failure-Message

[pine5514]

Hi,
I am using PF 13.1 with AD as authentication source. the problem is that PF Web UI show the same Failure-Message for different problem. it shows :
Reason: chrooted_mschap: Invalid output from ntlm_auth: expecting 'NT_KEY: ' prefix

this is a complete error message in debug mode:

chrooted_mschap: Program returned code (0) and output 'NT Error: (3221225584, 'The user account is restricted so that it cannot be used to log on from the source workstation.')'
