(0000818) oka (administrator) 2010-04-20 16:47	Hello, SVNKit uses SASL support that is built into JVM. First, make sure you're using JDK 1.5 or newer, as there is no SASL support in older versions. Then, take into account that JVM SASL support limited number of authentication types over SASL. I.e. it does support DIGEST-MD5, CRAM-MD5, but I doubt it supports NTLM. Refer to this article for more information on how to configure server-side SASL with DIGEST-MD5 mechanism: http://www.question-defense.com/2009/04/29/svn-checkout-svn-cannot-negotiate-authentication-mechanism [^] Also, make sure min-encryption option is set below 128 (i.e. 64), as JDK may not support higher encryption values.
