Sorry I forgot some informations. The error is : 1789, 'LookupAccountName', "The trust relationship between this workstation and the primary domain failed."
As I said, this doesn't always happen, sometimes logon runs successfully and ACLs are correctly set (this is why I use 'LookupAccountName'). If I try it in command line, the try/except statement is correctly run : >>> import win32security as wsec >>> wsec.LookupAccountName('','DomainUsers') # this should be working (<PySID object at 0x00A18A98>, u'CONDA', 2) >>> wsec.LookupAccountName('fakeserver','DomainUsers') # this not Traceback (most recent call last): File "<stdin>", line 1, in <module> pywintypes.error: (5, 'LookupAccountName', 'Access denied.') >>> try:wsec.LookupAccountName('fakeserver','DomainUsers') ... except: print 'oo' ... oo Thanks in advance. le dahut wrote : > Hello, > > I'm using this code : > mypdc = 'mypdc' > dusers = 'DomName\DomainUsers' > obj = 'C:\\Mylogfile.log' > try: > domainusers_sid = wsec.LookupAccountName(mypdc, dusers)[0] > info = wsec.DACL_SECURITY_INFORMATION > sd = wsec.GetFileSecurity(obj, info) > acl = sd.GetSecurityDescriptorDacl() > acl.AddAccessAllowedAceEx(wsec.ACL_REVISION_DS, > wsec.OBJECT_INHERIT_ACE, wf.FILE_ALL_ACCESS, domainusers_sid) > # maj du Security Descriptor > sd.SetSecurityDescriptorDacl(1, acl, 0) > # application sur l'objet > wsec.SetFileSecurity(obj, info, sd) > except Exception, e: > logging.error("ACLs error %s"%([obj, dusers, e])) > logging.debug('Error %s'%traceback.print_exc()) > > At logon time, it can occur that wsec.LookupAccountName fails.
