RE: SVN re-requests authentication for LOCK operation

Hi George

Thanks for your prompt reply. We do indeed seem to have the situation you describe. When users do an update/commit, the authentication data is automatically given to the apache svn server, and the data is saved in the %APPDATA%\Subversion\auth\svn.ssl.server directory. However, when users attempt to acquire a lock it would appear that subversion looks in the %APPDATA%\Subversion\auth\svn.simple directory for saved authentication. When it finds nothing there, it prompts the user instead of automatically providing the domain authentication. Unfortunately users requesting locks must be authenticated so we can't make use of your suggestion of the "<LimitExcept LOCK>" directive.

I am not sure whether this is a subversion or Tortoise SVN issue or whether it is a bug/feature. Any suggestions how to get around this issue would be much appreciated.

Hi Sam

we observed a similar behaviour when entering svn ls -R

In our case the authentication token was stored in the
%APPDATA%\Subversion\auth\svn.simple directory instead of the
%APPDATA%\Subversion\auth\svn.ssl.server directory as for the other
requests. Our work around was to grant all users read access as
default and configure Apache with

<LimitExcept PROPFIND>
  Require valid-user

Probably you have to change it to <LimitExcept LOCK> but check if
this is a behaviour you can accept.

I don't know if this is the intended behaviour or a bug.
