We have already configured SCM for LDAP authentication to a MS-Active Directory LDAP server. An update to LDAP was recently applied for security reasons. After applying the update our Harvest users could no longer login since Harvest could not authenticate users anymore. Does SCM supports TLS version 2.1 and SSL.
CA Harvest SCM version 12.5
You are on r12.5 release 
TLS version support is more of O.S dependent 
r12.5 is supported on Windows 2012

For Solaris which is your platform I think TLS version 1.2 is not supported.Please see the link
