Authentication token not valid for non-owner Plex Home users

I'm confused how Plex Home uses tokens to authenticate users and I can't get authentication for all users to work. 

Using the following Python script I am able to use the username and password of a Plex user to obtain a token.

import httplib, urllib, base64
username = "insertanyusernamehere"
password = "insertcorrespondingpasswdhere"
base64string = base64.encodestring('%s:%s' % (username, password)).replace('
', '')
txdata = ""

headers={‘Authorization’: “Basic %s” % base64string,
‘X-Plex-Client-Identifier’: “Test script”,
‘X-Plex-Product’: “Test script 356546545”,
‘X-Plex-Version’: “0.001”}

conn = httplib.HTTPSConnection(“plex.tv”)
conn.request(“POST”,"/users/sign_in.json",txdata,headers)
response = conn.getresponse()
print response.status, response.reason
data = response.read()
print str(data)
conn.close()

The script returns some user info, including a token. Next, I try to use the token to access the Plex API with the following script:

import httplib, urllib, base64

token = "INSERTTOKENHERE"

txdata = “”

headers={‘X-Plex-Client-Identifier’: “Test script”,
‘X-Plex-Product’: “Test script 356546545”,
‘X-Plex-Version’: “0.001”,
‘X-Plex-Token’: token}

conn = httplib.HTTPConnection(":32400")
conn.request(“GET”,"/library",txdata,headers)
response = conn.getresponse()
print response.status, response.reason
data = response.read()
print str(data)
conn.close()

When I enter the account credentials of the server's owner in the first script and insert the corresponding token into the second script, I get some info about the libraries on the Plex server, as expected. However, when I enter the credentials of any other Home user the first script returns a token successfully, but the second script returns a 401 Unauthorized error.  

 

Can someone tell me what I've been doing wrong?

 

I followed the instructions in this thread and posted my question there too, but I received no help there. 

I am experiencing the same issue. Did you ever figure out what the problem was or the correct method to implement non owner accounts?
