+### Please describe the problem.
+
+For shared repositories git annex refuses to move file out of repository (git annex move --to) if user triggering the move is not the owner of the file.
+
+### What steps will reproduce the problem?
+
+ * Init two shared repositories and create a file
+ * Modify that file in repo1 as user u1
+ * Move the file to repo2 as "repository maintenance" user u2
+ - this gives permission denied error
+
+Alternatively -- mabye better understandable usecase(repository maintainer moves unused files to backup):
+
+ * Init two shared repositories and create a file
+ * Modify that file in repo1 as user u1
+ * Modify that file in repo1 a second time (regardless which user) -- this makes the version edited by u1 unused
+ * Display unused files as repository maintenance user u2
+ - this gives permission denied error
+ * Move unused files to repo2 as "repository maintenance" user u2
+ - this gives permission denied error
+
+### What version of git-annex are you using? On what operating system?
