Hello everybody,
as many others before we wanted to do single-sign-on for intranet web
applications using integrated windows authentication (negotiate because
IE sometimes tries NTLM instead of using plain kerberos - breaking all
our kerberos-only experiments).
We thought that IIS would be the best choice for integrated windows
authentication and we could pass the user via AJP (using mod_jk) to our
tomcat instances.
Our setup:
- Windows 2008 R2 using IIS 7.5 (64bit)
- mod_jk 1.2.31
- Oracle Java 1.6 U24
- Tomcat 6.0.32
At first glance using tomcatAuthentication=false worked as expected. We
got the remote user and started deploying an application. End of
happiness - the application complained about a missing user-agent. That
header was not passed to tomcat when authentication was enabled on IIS.
Some research revealed Bug 47679 - Not all headers get passed to Tomcat
server from isapi_redirect.dll
(https://issues.apache.org/bugzilla/show_bug.cgi?id=47679)
Today I've found Bug 49318 - add a Negotiate (Kerberos/NTLM)
authenticator / integrate Waffle
(https://issues.apache.org/bugzilla/show_bug.cgi?id=49318). The last
comment links a new Windows Authentication How-To from Mark Thomas.
Looks like we have already tried almost all proposed solutions:
- IIS + mod_jk:
tried but stuck in Bug 47679. Also tried ARR to pass the user name
as a request header from IIS to Tomcat without success
- Apache mod_ntlm: used it and we replaced it by the much more stable
mod_auth_ntlm_winbind. NTLMv1 is also disabled on Windows 7 (default)
- Apache mod_auth_ntlm: in heavy use but stuck to Apache 2.0 and 32bit
plattform - we couldn't get stability problems solved on Apache 2.2
and 64bit Linux. No ongoing development.
- Apache mod_auth_sspi: till now in internal use for a very small
project (works just fine), not sure about the future. Although
there seems to be some new activity on 1.0.5 beta
- Waffle: found it on thursday and it is on my our todo-list for
testing it next week
Any chances to get Bug 47679 solved? How can we help (we are admins, no
devs)?
What solutions have you deployed? Recommendations?
Thank you,
Stefan Mayr
