The bloomin' Irish

Let me first apologise for asking on two lists, but this problem is (of
course) urgent because prior to this afternoon I was unaware of the problem
and it has been affecting production users for two days despite me having
warned everyone that they should be looking out for possible Samba problems!

I have just upgraded most of our samba servers from 1.9.18 (various patch
levels) to 2.2.2 on Solaris 8 and Solaris 2.6.  This was forced by an
upgrade of the Windoze password server from NT4 to Win2K.  Patch levels of
1.9.18 prior to (about) 10 would not work with the new server.  Patch level
10 does, luckily and remains on a system about to be retired.

We now have another problem.  Our file contains a few Irish
characters with apostrophes in their NT login names (e.g. O'Nerk.Fred) which
are all of the format lastname.firstname.

When these users now try to attach to a share the name get mangled by samba,
changing the apostrophe to an underscore (ie o_nerk.fred) as well as the
ussual case mangling and this results in a login failure.  On the 1.9.18p10
system no such mangling occurs.

I have searched archives of both lists and found only one entry about 18
months ago where someone asked if this would work.  I have also searched
most of the docos and not found a solution.

Does anyone on the lists have the (probably bleeding obvious) answer?
Relevant smb.conf entries (this file wasn't changed between versions and
passes testparm on 2.2.2 except mysteriously for "share modes".)

  workgroup = COMCARE
  security = server
  password server = act-primary
  encrypt passwords = yes
  wins server = act-secondary
  username map = /usr/local/samba/lib/
  domain master = no
  local master = no
