In the meantime it turned out that the right to logon interactively
should also be given to the cyg_server account. Otherwise you get
spurious logon failure events in the security event on the DC related to
the cyg_server account.
While I'm at it, I'd like to propose the following changes as well:
- Don't test for the "Deny Logon" rights in
csih_account_has_necessary_privileges. After all, these rights are
only additional security measures, but not at all necessary to do the
job.
- Don't test or set the SeIncreaseQuotaPrivilege privilege. This is
given to Administrators by default anyway and if the right is not
given to cyg_server explicitely, the test will fail, because
editrights doesn't test the groups in the token, only the user itself.
Actually that's something which would be worth a fix to editrights.
So the patch I propose looks like this:
* cygwin-service-installation-helper.sh
(csih_account_has_necessary_privileges): Don't explicitely test for
SeDenyXXX rights, nor for SeIncreaseQuotaPrivilege.
(csih_create_privileged_user): Drop setting SeDenyInteractiveLogonRight,
SeDenyNetworkLogonRight, and SeIncreaseQuotaPrivilege.
