Important functionality currently missing from PyKerberos, is the ability for a middle tier server to reuse the client's credentials to authenticate against another server (credential delegation). A previous ticket (submitted by Daniel) kindly added a patch for this, but the patch also contained a number of other changes which may prevent the delegation work from being committed to trunk. Ticket (*#847*) contains just the delegation work submitted by Daniel, which I hope will expedite these changes into trunk - as I feel this is very valuable functionality. Could these changes please be considered for trunk. If I have to make a request elsewhere, please let me know. All the very best, Marc
