AW: AW: ISAPI Redicect - Request Entitiy too large

2011-10-06 Thread Alexander Diedler
Yes, that´s it. We changed the size to 12k and everything works fine.
It is a lot tricky, that the default value is not fitting in a default
environment.
Thanks to all for your help.

Alex

Alexander,

If you are using authorisation header, then you are using SPNGEO. This
header encodes the users group membership in the authorisation header. By
default tomcat has an 8k maximum header, whilst users belonging to many
groups can have an authorisation token that can swell to larger than this
size. This explains why you see some people can login and others can't.

Just change the maxHttpHeaderSize to something larger than the default 8k
and you should be set. We used 32k

AW: ISAPI Redicect - Request Entitiy too large

2011-10-05 Thread Alexander Diedler
Hello,
We use the IIS integrated (Windows) domain authentication, which is passed
to the Tomcat and then we check the given String with our user database in
the app and if username and password match, the user was automatically
logged in (SSO).

Greetings
Alexander

 Hello @ll,
 
 I have installed a new Windows 2008 R2 x64 Server with IIS7 and Tomcat
 6.0.32 x64 Edition. We use SSO Authentication from IIS to the Tomcat.

Which SSO mechanism ?

 Suddenly, we got on some clients, but not on every client (that´s 
 stupid!) the following error:
 
  
 
 Request Entity Too large!

which does look strange, considering that there is a Content-length: 0
header below.

It looks a bit as if a HTTP *header* in the request was too large.

Repeat question : can you be a bot more specific about the authentication
mechanism used ?
Also, if you can determine a difference, what is the difference between the
clients where it happens, and the ones where it does not ?

Ok, basically thanks.  I just wanted to know if the NTLM authentication dialog could 
explain some extra-large headers.
But in this case, apparently not, since the authentication dialog happens between the 
browser and IIS, and should not even be seen in Tomcat.

(Apart from the final Authorization: header).

One item in your above explanation does not fit : username and password cannot be. 
There is no way that the IIS authentication would produce a user password that you can 
pass on to Tomcat. Userid yes, password no.

(But it does not matter for the current issue).

Anyway, what about a difference between the workstations for which it happens, and the 
ones for which it does not ? any visible OS/browser difference ?

Addendum : can you increase the log level of isapi_redirect on the IIS server, and try 
again ? it may show us a bit more about what is happening.

Betreff: Re: AW: ISAPI Redicect - Request Entitiy too large

Addendum : can you increase the log level of isapi_redirect on the IIS
server, and try again ? it may show us a bit more about what is happening.

Alexander,

If you are using authorisation header, then you are using SPNGEO. This
header encodes the users group membership in the authorisation header. By
default tomcat has an 8k maximum header, whilst users belonging to many
groups can have an authorisation token that can swell to larger than this
size. This explains why you see some people can login and others can't.

Just change the maxHttpHeaderSize to something larger than the default 8k
and you should be set. We used 32k
