To encrypt LDAP bind password in zeppelin Shiro configuration follow below steps:

1. Removed system password line from the config (this line contained the password for the system user that is doing the LDAP lookups) 
2. Added the following line in shiro.ini: 

ldapRealm.hadoopSecurityCredentialPath=jceks://file/home/zeppelin/conf/zeppelin.jceks 

3. Run the following command as Zeppelin user on Zeppelin host: 

# hadoop credential create ldapRealm.systemPassword -provider jceks://file/home/zeppelin/conf/zeppelin.jceks 
#Entered password <test> 

Where <test> is my password
