@@ -7,6 +7,15 @@ wallet 1.3 (xxxx-xx-xx) generate content for the object if you do a get before storing any content inside it. + Added a new command to wallet-backend, update. This will update the + contents of an object before running a get on it, and is only valid + for objects that can automatically get new content, such as keytab + and password objects. A keytab will get a new kvno regardless of + the unchanging flag if called with update. In a future release get + will be changed to never update a keytab, and the unchanging flag + will be ignored. Please start moving to use get or update as the + situation warrants. + Added an acl replace command, to change all objects owned by one ACL to be owned by another. diff --git a/client/wallet.pod b/client/wallet.pod index 20d1874..672f0e4 100644 --- a/client/wallet.pod +++ b/client/wallet.pod @@ -385,6 +385,19 @@ If an object with type <type> and name <name> does not already exist when this command is issued (as checked with the check interface), B<wallet> will attempt to automatically create it (using autocreate). +=item update <type> <name> + +Prints to standard output the data associated with the object identified +by <type> and <name>, or stores it in a file if the B<-f> option was +given.
