Description:
NSS 3.14 deprecates the current way to configure SSL versions:
SSL_OptionSet(pr_sock, SSL_ENABLE_SSL3|SSL_ENABLE_TLS, True|False)
Instead, it introduces new range APIs to provide more detailed SSL
version control by using SSL_VersionRangeSet(pr_sock, NSSVersions).
The NSSVersions has 2 fields "min" and "max", which take the minimum
and maximum SSL versions.

By default, slapd_ssl_init2 sets the default supported range by NSS,
which is min: SSL3 and max: TLS1.2. This patch adds 2 config params
sslVersionMin and sslVersionMax to cn=encryption,cn=config to provide
the ability to control the values.

Both takes: ssl3 or tls1.?. If the range is not supported by the
NSS or conflicts with the current params nsSSL3 and nsTLS1, it'd be
adjusted.

should be sslVersionMax-oid to be consistent.

Please change "valud" to "value"

Otherwise, ack

Rich, thank you for pointing out the typos!!

Revised and pushed to master:
9357bf1..88d4bec master -> master
commit 88d4bec

Description: commit 88d4bec always
expected the NSS version supporting TLS 1.2. It broke the build on
the system having the NSS version that only supports TLS 1.1 (and
older). This patch checks the NSS version and switches the supported
TLS in ssl.c based upon the version info.

Looks like there is logging early on in the startup process:

[05/Dec/2013:15:05:28 -0500] SSL Initialization - supported range: min: SSL3, max: TLS1.1

I see this on the command line when I restart my instances - as the error log has probably not been initialized yet. I don't think this should be displayed when restarting an instance. Can we remove this, or move it somewhere else where it won't go to stdout? Do you agree? Thoughts?
