# Validate Group Replication behavior when members have disjoint TLS versions.
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Setup the first member (M1) with a recovery user that requires TLS 1.3.
# 2. Add some data and bootstrap start a group on M1.
# 3. Configure a joining member (M2) to use SSL options and a different
#    TLS version on recovery. Member will not be able to join.
# 4. Configure a joining member to use SSL options and the same
#    TLS version on recovery. Member will be able to join.
# 5. Clean up.
