block the creation of new branches

Good day for everybody we want to lock down the creation of new branches in a project, but we want to still using the existing branches, we should be able to commit code to those branches as normally  is that possible?  I added this to my svn_access_file [sandbox:/test1/branch] * = r  this configuration blocks the creation of new branches but also sets all branches as read only, that doesn't work for me because I need to be able to commit code to the existing branches.  hope you can help me, thanks a lot.

What version of SVN are you using? If you're using SVN 1.10 (or later) then you can use wildcards and the following should work: 

[sandbox:/test/branch] *=r  [:glob:sandbox:/test/branch/*] *=rw

   Prior to that release you would need to create a different section for every existing branch. Update if you need to!
