[IRCServices] bug in UNBAN?

[Alexander Janssens]

[13:27:51] -> Server: mode #help +b *!*Alex*@*
[13:27:51] * _-Alex-_ sets mode: +b *!*Alex*@*
[13:28:07] -> Server: chanserv unban #help
[13:28:07] * ChanServ sets mode: -b *!*Alex*@*
[13:28:07] [CS] You have been unbanned from #help.

Here it seems to work correctly

[13:28:20] -> Server: mode #help +b *!*alex*@*
[13:28:20] * _-Alex-_ sets mode: +b *!*alex*@*
[13:28:22] -> Server: chanserv unban #help
[13:28:22] [CS] You have been unbanned from #help.

Here it claims to remove the ban, but it didn't do so.  I checked with /mode
#help +b  and the ban was still there, trying to rejoin didn't work, I was
banned.

_-Alex-_ is Alex at crew.something
_-Alex-_ @#help
_-Alex-_ has identified for this nick
_-Alex-_ is an IRC Operator - Server Administrator
_-Alex-_ End of /WHOIS list.

as my /whois indicates, my ident starts with an uppercase 'a', so it seems
services dont take alex equal to Alex, which it should for hostmasks in the
banlist.  If I try to unban manually, it works no matter if I use *!*Alex*@*
or *!*alex*@*.

Conclusion: as far as I can see, the ircd does not make a difference between
the upper or lowercase letter, services seem to do so.  I doubt this is
correct as that would make banevading really easy.

We're runnig ircservices 5.0.2 on bahamut 1.4.34
