Add missing salt from enctype in t_kdb.py test

[pkis]

kadmin requires enctypes in form "key:salt"
If it is not given in that form, it reports error and the test fails.

The issue might remain hidden because the test is executed only if ldap is installed. If missing, the test silently passes (only the verbose output shows more detail).

kadmin has allowed the salt to be omitted in keysalt lists since cc26d29 (RT #884). I am curious what circumstances led to running new t_kdb.py tests against an old version of kadmin.

Ah, this is my fault, sorry, I ran the test from 1.12-2, where the test t_kdb.py was failing and I did not check it in the latest version. Checking it again, the branch 1.12 contains the test t_kdb.py but is missing the fix from RT #884, so this is still a problem, but I obviously reported it against the wrong branch.
Ok, so the test in the master branch is working. The question is then, should this be reported against 1.12? Or better I should ask, does it make sense to report problems against 1.12 (are there plans to release 1.12-3)?

Thanks for the clarification. You appear to be right, and your patch looks like a correct fix for the problem. Tom can apply it to the 1.12 branch, and it will go into the 1.12.3 release whenever that comes out.
