Has the cache_credentials default changed in SSSD?

During a recent audit of RHEL6 server configuration I identified what appears to be a change in the default configuration of the cache_credentials option in sssd. The documentation states that the default value for cache_credentials is false, but I am seeing the opposite.

The /etc/sssd/sssd.conf file in question does not specify a value for the cache_credentials option, and when running authconfig --test I get the following result:

 credential caching in SSSD is enabled

If I add the following to the sssd.conf file in the domain section:

cache_credentials = false

authconfig --test now shows the following (expected) result:

 credential caching in SSSD is disabled

The documentation (included man page) explicitly states that the default value is FALSE

       cache_credentials (bool)
           Determines if user credentials are also cached in the local LDB cache

           User credentials are stored in a SHA512 hash, not in plaintext

           Default: FALSE

The installed version of sssd is sssd-1.12.4-47.el6_7.7.x86_64

Has anyone else seen this? or is anyone else able to replicate this issue?
