Mesos SSL problems

Configuration

In /etc/default/mesos

export SSL_ENABLED=true
export SSL_SUPPORT_DOWNGRADE=false
export SSL_REQUIRE_CERT=true
export SSL_CERT_FILE=/etc/mesos/tiger-jdoe-controller-1.tiger.acme.net.crt
export SSL_KEY_FILE=/etc/mesos/tiger-jdoe-controller-1.tiger.acme.net.key
export SSL_CA_FILE=/etc/mesos/rootCA.pem

Problem #1 slaves can't connect to master over SSL

In master logs:

W0917 10:10:55.881906 23468 openssl.cpp:237] Error with certificate at depth: 0
Issuer: /C=US/ST=CA/O=acme/OU=Tiger
Subject: /C=US/O=acme/OU=Tiger/CN=tiger-jdoe-worker-2.tiger.acme.net
Error (26): unsupported certificate purpose

but slave cert has what I believe are correct certificate purposes

# openssl x509 -in /etc/mesos/tiger.crt -noout -purpose
Certificate purposes:
SSL client : Yes
SSL client CA : No
SSL server : Yes
SSL server CA : No
Netscape SSL server : Yes
Netscape SSL server CA : No
S/MIME signing : No
S/MIME signing CA : No
S/MIME encryption : No
S/MIME encryption CA : No
CRL signing : No
CRL signing CA : No
Any Purpose : Yes
Any Purpose CA : Yes
OCSP helper : Yes
OCSP helper CA : No
Time Stamp signing : No
Time Stamp signing CA : No

Problem #2 can't connect to master if cert validation is enabled

SSL_REQUIRE_CERT implies SSL_VALIDATE_CERT, and failed to connect with curl even enabling all protocols

With this config in the master

SSL_CA_FILE=/etc/mesos/rootCA.pem
SSL_CERT_FILE=/etc/mesos/tiger.crt
SSL_ENABLED=true
SSL_ENABLE_SSL_V3=true
SSL_ENABLE_TLS_V1_0=true
SSL_ENABLE_TLS_V1_1=true
SSL_KEY_FILE=/etc/mesos/tiger.key
SSL_REQUIRE_CERT=true
SSL_SUPPORT_DOWNGRADE=false

hostname manually set to tiger-jdoe-controller-1.tiger.acme.net to ensure SSL hostname validation works

Master running with

/usr/sbin/mesos-master --zk=zk://zk:xxxxxx@10.16.2.1:2181/mesos --port=5050 --log_dir=/var/log/mesos --authenticate=true --authenticate_slaves=true --credentials=/etc/mesos/credentials --hostname=tiger-jdoe-controller-1.tiger.acme.net --quorum=1 --work_dir=/var/lib/mesos

Different curl versions fail to connect to master when providing a client certificate
