Greetings. First, Zope and Plone look like excellent products. I look forward to using them and learning more about them. I have scoured the archives and google and haven't found what I'm looking for. Hopefully, someone here can help with some quick advice. I am looking for an issue tracker for us internally for bugtracking as well as for external users for support. I am leaning toward PloneCollectorNG, but I have some requirements that may be problematic: The users must log into the system via our two-factor authentication product. This is why I chose a zope-based product: the exuserfolder supports Radius. I can get exuserfolder working with WiKID via Radius and I can get PloneCollectorNG working without radius, but I can't get them both working at the same time. I'm guessing it has something to do with User management and groups. I can add issues, but I can't add staff. I am running on Fedora Core 2, with zope-2.7.2, plone-2.0.4 (installed via apt-get), exUserFolder-0_20_1, PloneCollectorNG-1.2.4. Here is the error I get: Traceback (innermost last): Module ZPublisher.Publish, line 101, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Shared.DC.Scripts.Bindings, line 306, in __call__ Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec Module Products.CMFCore.FSPageTemplate, line 191, in _exec Module Products.CMFCore.FSPageTemplate, line 124, in pt_render Module Products.PageTemplates.PageTemplate, line 96, in pt_render <FSPageTemplate at /test/test/pcng_staff used for /test/test/plonecollectorng.2004-11-05.6293294645> Module TAL.TALInterpreter, line 189, in __call__ Module TAL.TALInterpreter, line 233, in interpret Module TAL.TALInterpreter, line 670, in do_useMacro Module TAL.TALInterpreter, line 233, in interpret Module TAL.TALInterpreter, line 408, in do_optTag_tal Module TAL.TALInterpreter, line 393, in do_optTag Module TAL.TALInterpreter, line 388, in no_tag Module TAL.TALInterpreter, line 233, in interpret Module TAL.TALInterpreter, line 701, in do_defineSlot Module TAL.TALInterpreter, line 233, in interpret Module TAL.TALInterpreter, line 408, in do_optTag_tal Module TAL.TALInterpreter, line 393, in do_optTag Module TAL.TALInterpreter, line 388, in no_tag Module TAL.TALInterpreter, line 233, in interpret Module TAL.TALInterpreter, line 649, in do_defineMacro Module TAL.TALInterpreter, line 233, in interpret Module TAL.TALInterpreter, line 693, in do_defineSlot Module TAL.TALInterpreter, line 233, in interpret Module TAL.TALInterpreter, line 610, in do_loop_tal Module Products.PageTemplates.TALES, line 206, in setRepeat Module Products.PageTemplates.TALES, line 221, in evaluate Line 34, Column 8 Expression: <PythonExpr (('Assigned', here.getTrackerUsers(staff_only=1,with_groups=1)), ('Unassigned', here.getTrackerUsers(unassigned_only=1,with_groups=1)))> Names: {'container': <PloneSite instance at f5901350>, 'context': <PloneCollectorNG instance at f59017d0>, 'default': <Products.PageTemplates.TALES.Default instance at 0xf66d2a4c>, 'here': <PloneCollectorNG instance at f59017d0>, 'loop': <SafeMapping instance at f290a790>, 'modules': <Products.PageTemplates.ZRPythonExpr._SecureModuleImporter instance at 0xf666cccc>, 'nothing': None, 'options': {'args': ()}, 'repeat': <SafeMapping instance at f290a790>, 'request': <HTTPRequest, URL=http://65.182.34.70:8080/test/test/plonecollectorng.2004-11-05.6293294645/pcng_staff>, 'root': <Application instance at f5e3b470>, 'template': <FSPageTemplate at /test/test/pcng_staff used for /test/test/plonecollectorng.2004-11-05.6293294645>, 'traverse_subpath': [], 'user': nowen} Module Products.PageTemplates.ZRPythonExpr, line 47, in __call__ __traceback_info__: (('Assigned', here.getTrackerUsers(staff_only=1,with_groups=1)), ('Unassigned', here.getTrackerUsers(unassigned_only=1,with_groups=1))) Module Python expression "(('Assigned', here.getTrackerUsers(staff_only=1,with_groups=1)), ('Unassigned', here.getTrackerUsers(unassigned_only=1,with_groups=1)))", line 1, in <expression> Module Products.PloneCollectorNG.Collector, line 255, in getTrackerUsers TypeError: iteration over non-sequence Thanks in advance, any suggestions much appreciated.
