Apache-AuthenNTLM
view release on metacpan or search on metacpan
0.15 9. Apr 2002
- Added patch from Brian Paulsen which causes correct handling of
non unicode charset (needed for some versions of win9x) and
more verbose debugging output (decoded flags)
0.14 26. Feb 2002
- fixed a problem that page content of Perl sometimes goes to the
stderr instead of stdout
0.13 9. Jan 2002
- return mapped username, when second request on same connection,
instead of unmapped
0.12 8. Jan 2002
- fix broken Authen::Smb::authen function in Authen::Smb 0.92 that
ships with Apache::AuthenNTLM
