Subject: [PATCH] Remove confvalidator utility
This utility has not been maintained with encryption types and salt
changes, which suggests it is unused.
(cherry picked from commit 482a366793d9338e9edb504b407d7704a4bb2f8f)

-validator.py is a command line tool for identifying invalid attributes, values and some formating problems in Kerberos configuration files.
-The list of the valid attributes is created based on the “configuration variables” section in k5-int.h and user defined attributes from the rules file.
-
-Usage:
-
-validator.py path [-d defPath] [-r rulesPath] [-c validatorConfPath]
-
-Options:
-
-path –
-
--d defPath –
-
--r rulesPath - path the rules file in yaml format. It may be used to manage the list of the valid attributes and to define the additional validation rules.
-
--c validatorConfPath –
-
-Example:
-
-python validator.py src/config-files/krb5.conf -r rules.yml -d src/include/k5-int.h
-or
-python validator.py src/config-files/krb5.conf -c validator.conf
-
-For more details please refer to the sample files validator.conf and rules.yml
