  38 <PRE>Hi,
  39
  40 yesterday, a user told our staff that he was not able to op users who were
  41 not on the channel's access list.
  42
  43 [19:41:58] *** Mode change [+o testuser] on channel #quizzing by papillio
  44 [19:41:58] *** Mode change [-o testuser] on channel #quizzing by ChanServ
  45
  46 =ChanServ=   Information for channel #quizzing:
  47 =ChanServ=   Options: Topic Retention, Op-Notice
  48
  49 As you can see, Secureops is deactivated.
  50
  51 Trying to op via '/chanserv op #quizzing testuser' results in:
  52 =ChanServ=   Unable to op testuser on channel #quizzing.
  53
  54 On our network, we've been using Services5 for about a month. Before, we
  55 used Services4; the channel #quizzing was registered under version 4 and the
  56 founder modified the level settings completely. He also set AUTODEOP to
  57 level 4. This was the problem:
  58
  59 After some investigation I found out that the level settings were
  60 _completely_ taken over to Services5, including the level settings of
  61 AUTODEOP and NOJOIN. As you know, in Services5 AUTODEOP and NOJOIN should
  62 always be fixed to -1 and -100, and they are invisible to the user. To check
  63 this, I modified services to also show those two levels in '/chanserv levels
  64 list':
  65
  66 =ChanServ=   Access level settings for channel #quizzing:
  67 [...]
  68 =ChanServ=   _AUTODEOP     40
  69 =ChanServ=   _NOJOIN      -20
  70 [...]
  71
  72 The values were simply converted (new level=old level*10 in this case) like
  73 any other level and are also being used to check user rights.
  74
  75 So if you have registered channels with Services4 with a positive AUTODEOP
  76 or NOJOIN level and then use Services5, users without an access list entry
  77 or too low access level may not be able to join the channel or get opped.
  78 Since NOJOIN and AUTODEOP-settings can't be changed in v5, the founder has
  79 to use '/chanserv levels reset' to work around this problem.
  80
  81 I was able to reproduce this bug with a new installation of Services 4.5.45
  82 with clean databases, then using Services 5.0.29.
  83 Hopefully this will get fixed in the next services release, i.e. by setting
  84 both levels to -1 and -100 after reading the database.
  85
  86 If there are any problems understanding me/the bug, please ask.. ;)
  87 Wolle
