+<1> If you specified `'insecure': 'false'`
+in the `openshift_master_identity_providers` parameter for only an LDAP identity
+provider, you can omit the CA certificate.
+<2> If you specify a file on the host you run the playbook on, its contents are
+copied to the
+*_/etc/origin/master/<identity_provider_name>_<identity_provider_type>_ca.crt_*
+file. The
+identity provider name is the value of the `openshift_master_identity_providers`
+parameter, `ldap`, `openid`, or `request_header`. If you do not
+specify the CA text or the path to the local CA file, you must place the CA
+certificate in this location. If you specify multiple identity providers, you 
+must manually place the CA certificate for each provider in this location. You cannot change this location.
+
+You can specify multiple identity providers. If you do, you must place the
+CA certificate for each identity provider in the *_/etc/origin/master/_* directory. 
+For example, you include the following providers in your
+`openshift_master_identity_providers` value:
+
+----
+openshift_master_identity_providers:
+- name: foo
+  provider:
+    kind: OpenIDIdentityProvider
+    ...
+- name: bar
+  provider:
+    kind: OpenIDIdentityProvider
+    ...
+- name: baz
+  provider:
+    kind: RequestHeaderIdentityProvider
+    ...
+----
+
+You must place the CA certificates for these identity providers in the following
+files:
+
+* *_/etc/origin/master/foo_openid_ca.crt_*
+* *_/etc/origin/master/bar_openid_ca.crt_*
+* *_/etc/origin/master/baz_requestheader_ca.crt_*
