Unable to authenticate to zeppelin UI

[#1]

Accessing zeppelin with pam credentials are failing with bad credentials

[#2 · Accepted solution]

Hello @Harish-hadoop 
Make sure zeppelin user has read permission on /etc/shadow file to authentication using pam

You can try setting the read permission with the below command on zeppelin host

# chmod 444 /etc/shadow
