# TESTING OF MULTIPLE AUTHENTICATION PLUG-INS
OpenVPN 2.x can support loading and authenticating users through multiple
plug-ins at the same time. But it can only support a single plug-in doing
deferred authentication. However, a plug-in supporting deferred
authentication may be accompanied by other authentication plug-ins **not**
doing deferred authentication.
This is a test script useful to test the various combinations and order of
plug-in execution.
The configuration files are expected to be used from the root of the build
directory.
To build the needed authentication plug-in, run:
make -C sample/sample-plugins
## Test configs
* Client config
verb 4
dev tun
client
remote x.x.x.x
ca sample/sample-keys/ca.crt
cert sample/sample-keys/client.crt
key sample/sample-keys/client.key
auth-user-pass
* Base server config (`base-server.conf`)
verb 4
dev tun
server 10.8.0.0 255.255.255.0
dh sample/sample-keys/dh2048.pem
ca sample/sample-keys/ca.crt
cert sample/sample-keys/server.crt
key sample/sample-keys/server.key
## Test cases
### Test: *sanity-1*
This tests the basic authentication with an instant answer.
config base-server.conf
plugin multi-auth.so S1.1 0 foo bar
#### Expected results
- Username/password `foo`/`bar`: **PASS**
- Anything else: **FAIL**
### Test: *sanity-2*
This is similar to `sanity-1`, but does the authentication
through two plug-ins providing an instant reply.
config base-server.conf
plugin multi-auth.so S2.1 0 foo bar
plugin multi-auth.so S2.2 0 foo bar
#### Expected results
- Username/password `foo`/`bar`: **PASS**
- Anything else: **FAIL**
### Test: *sanity-3*
This is also similar to `sanity-1`, but uses deferred authentication
with a 1 second delay on the response.
plugin multi-auth.so S3.1 1000 foo bar
#### Expected results
- Username/password `foo`/`bar`: **PASS**
- Anything else: **FAIL**
### Test: *case-a*
Runs two authentications, the first one deferred by 1 second and the
second one providing an instant response.
plugin multi-auth.so A.1 1000 foo bar
plugin multi-auth.so A.2 0 foo bar
#### Expected results
- Username/password `foo`/`bar`: **PASS**
- Anything else: **FAIL**
### Test: *case-b*
This is similar to `case-a`, but the instant authentication response
is provided first before the deferred authentication.
plugin multi-auth.so B.1 0 foo bar
plugin multi-auth.so B.2 1000 test pass
#### Expected results
- **Always FAIL**
- This test should never pass, as each plug-in expects different
usernames and passwords.
### Test: *case-c*
This is similar to the two prior tests, but the authentication result
is returned instantly in both steps.
plugin multi-auth.so C.1 0 foo bar
plugin multi-auth.so C.2 0 foo2 bar2
#### Expected results
- **Always FAIL**
- This test should never pass, as each plug-in expects different
usernames and passwords.
### Test: *case-d*
This is similar to the `case-b` test, but the order of deferred
and instant response is reversed.
plugin ./multi-auth.so D.1 2000 test pass
plugin ./multi-auth.so D.2 0 foo bar
#### Expected results
- **Always FAIL**
- This test should never pass, as each plug-in expects different
usernames and passwords.
### Test: *case-e*
This test case will run two deferred authentication plug-ins. This is
**not** supported by OpenVPN, and should therefore fail instantly.
plugin ./multi-auth.so E1 1000 test1 pass1
plugin ./multi-auth.so E2 2000 test2 pass2
#### Expected results
- The OpenVPN server process should stop running
- An error about multiple deferred plug-ins being configured
should be seen in the server log.
