I am running Red Hat Enterprise Linux Server release 6.9 (Santiago) in a docker container.

Executing:

$svn co svn://blah.company.com/directory

Getting:

svn: E170013: Unable to connect to a repository at URL 
'svn://blah.company.com/directory'
svn: E210007: Cannot negotiate authentication mechanism

SVN version:

$svn --version
svn, version 1.9.7 (r1800392)
   compiled Aug 10 2017, 19:20:08 on x86_64-redhat-linux-gnu

You need to install cyrus-sasl, cyrus-sasl-plain and cyrus-sasl-md5 (optional) packages.

The Subversion codebase returns this particular error (internal code SVN_ERR_RA_SVN_NO_MECHANISMS) when the Subversion client libraries are compiled against the Cyrus SASL libraries but, at runtime, cannot find an authentication mechanism which is accepted by the server.

You can see the developer notes about the bit of Subversion's functionality at: https://svn.apache.org/repos/asf/subversion/trunk/notes/sasl.txt

And here's a link to someone else who run into similar trouble, with hints on how you might fix your own situation: https://www.question-defense.com/2009/04/29/svn-checkout-svn-cannot-negotiate-authentication-mechanism

I don't have personal experience with this area of Subversion's functionality, but I'm assuming (based on this latter write-up) that it would be useful to know which SASL mechanisms are supported by the server you are trying to access.
