  34 <PRE>     I was under the impression usernames were matched case-sensitively,
  35 like in Unix; it appears that's not the case, so I've corrected the code
  36 to match case-insensitively.  Thanks for the report.

  48 </I>&gt;<i>Here it seems to work correctly

  53 </I>&gt;<i>[13:28:22] [CS] You have been unbanned from #help.
  54 </I>&gt;<i>
  55 </I>&gt;<i>Here it claims to remove the ban, but it didn't do so.  I checked with /mode
  56 </I>&gt;<i>#help +b  and the ban was still there, trying to rejoin didn't work, I was
  57 </I>&gt;<i>banned.

  59 </I>&gt;<i>_-Alex-_ is <A HREF="http://www.ircservices.za.net/mailman/listinfo/ircservices">Alex at crew.something</A>
  60 </I>&gt;<i>_-Alex-_ @#help
  61 </I>&gt;<i>_-Alex-_ has identified for this nick
  62 </I>&gt;<i>_-Alex-_ is an IRC Operator - Server Administrator
  63 </I>&gt;<i>_-Alex-_ End of /WHOIS list.
  64 </I>&gt;<i>
  65 </I>&gt;<i>as my /whois indicates, my ident starts with an uppercase 'a', so it seems
  66 </I>&gt;<i>services dont take alex equal to Alex, which it should for hostmasks in the
  67 </I>&gt;<i>banlist.  If I try to unban manually, it works no matter if I use *!*Alex*@*
  68 </I>&gt;<i>or *!*alex*@*.
  69 </I>&gt;<i>
  70 </I>&gt;<i>Conclusion: as far as I can see, the ircd does not make a difference between
  71 </I>&gt;<i>the upper or lowercase letter, services seem to do so.  I doubt this is
  72 </I>&gt;<i>correct as that would make banevading really easy.
  73 </I>&gt;<i>
  74 </I>&gt;<i>We're runnig ircservices 5.0.2 on bahamut 1.4.34
