[cvsnt] An unexpected error occurred during logon

[Adrian Herscu]

Hi all,

Using CVSNT version 2.0.58d.

While trying to cvs login as an NT user (even as Administrator) 
with a wrong password the login fails as expected.

While trying to cvs login as an NT user (even as Administrator) 
with the right password the login apparently succeeds, and the 
following event is logged to the system security log.

Moreover, trying to perform some cvs operation, such as 
checkout, commit, etc., fails with this message:

cvs [checkout aborted]: cvs [server aborted]: Repository 
directory E:/cvsrepo/<my repo> does not exist: Permission denied

and the same event is logged to the system security log.

1) Event data
Event ID: 537
User: NT AUTHORITY\SYSTEM
Logon Failure:
  	Reason:		An unexpected error occurred during logon
  	User Name:	
  	Domain:		
  	Logon Type:	3
  	Logon Process:	CVSNT
  	Authentication Package:	Negotiate
  	Workstation Name:	-

2) cvsservice.exe process is configured to run under LocalSystem 
account (and the service is allowed to interact with desktop) 
and the following *disabled* privileges showup in the process 
explorer:
SeAssignPrimaryTokenPrivilege
SeBackupPrivilege
SeCreateTokenPrivilege
SeIncreaseQuotaPrivilege
SeLoadDriverPrivilege
SeRestorePrivilege
SeSecurityPrivilege
SeShutDownPrivilege
SeSystemEnvironmentPrivilege
SeSystemtimePrivilege
SeTakeOwnershipPrivilege
SeUndockPrivilege

3) CVS repository allows full control to Administrators and 
SYSTEM accounts.

4) CVS temporary directory allows full control to Everyone.

5) The NT users have the following rights:
Access this computer from the network
Log on locally
Log on as batch job

NOTE: I have used version 2.0.41a and it worked correctly. 
Suddenly, after few MS patches, it found that I cannot 
add/commit/checkout files and tried to upgrade to version 
2.0.58d, which did not solve the problem. As far as I know to 
this moment, everything else works as usual.

Thanks for your time,
Adrian.
