Cyrus SASL with NTLM and SMB Signing

Hi,

I know that this problem is not strictly SVN specific, but maybe one of the users here has experience with this and knows a solution:

I'm currently trying to set up an SVN server on linux which authenticates against an Windows domain using NTLM - we want a single sign-on solution.

The version of SASL is the debian libsasl2-2 package in version 2.1.25.dfsg1-6+deb7u1 (debian wheezy on amd64) running with SVN 1.6.17 (but upgrading to SVN 1.7 or 1.8 is an option.)

The configuration on the server side seems to be correct, but the authentication fails with the following message:
NTLM: error in NEGPROT response parameters

As far as I could google it[1], there seems to be a workaround (disabling SBM signing via group policy), but said workaround is not acceptable for our network administrators. The SMB Signing seems to be a security feature which is enabled by default on windows servers since 2003.

Is there any other solution or workaround for this problem?

Best regards

Markus Schaber
