Hi Team,

I am not able to login with LDAP user. I set the adminAuth with "node-red-contrib-ldap-auth", "node-red-auth-contrib-ldap". I am getting the below error:

{"error":"invalid\_grant","error\_description":"Invalid resource owner credentials"}

How to proceed here. I am pasting the adminAuth code which i tested with. Please let me know if am doing anything wrong.

adminAuth: require('node-red-contrib-ldap-auth').setup({  
uri: 'ldap://Alpha-PA.security.com',  
base: 'dc=SECURITY,dc=com',  
filterTemplate: 'user={username}',  
bind\_dn: 'cn=Administrator,cn=Users,dc=security,dc=com',  
bind\_pw: '\*\*\*\*\*\*\*'  
}),
