SSO wrong password issue

Hi,

Some while back the sso was installed with admin password, now when the password changed, I'm getting the following errors:

info '[SSO]' opID=5c244f32] [UserDirectorySso] Authenticate(xxx\administrator, "not shown")

error '[SSO]' opID=5c244f32] [UserDirectorySso] AcquireToken InvalidCredentialsException: Authentication failed: User Account is locked

error 'authvpxdUser' opID=5c244f32] Failed to authenticate user <xxx\administrator>

Where can I update/change password for the account?

after I have collected the logs it appeared in \Logs\vpxd\vpxd-777.log

Thank you.
