Subject Re: Is LDAP connection failing?
Date Thu, 05 Apr 2018 16:50:22 GMT
Hello Suvendu,

May I ask you to share your JNDIRealm configuration?

For me something like this works:

 <Realm className="org.apache.catalina.realm.JNDIRealm"
     connectionURL="ldaps://my.users.directory.com:636"
     connectionName="CN=MY_BINDING_USER,OU=Users,OU=Organic
Units,DC=cern,DC=ch"
     connectionPassword="PASSWORD"
     userBase="OU=Users,OU=Organic Units,DC=cern,DC=ch"
     userSubtree="false"
     userPattern="cn={0},OU=Users,OU=Organic Units,DC=cern,DC=ch"

 roleBase="OU=BASE_ORGANIZATION_UNIT_FOR_MY_GROUPS,OU=Workgroups,DC=cern,DC=ch"
     roleSubtree="1"
     roleName="cn"
     roleSearch="(&amp;(member={0})(objectclass=group))"
/>

Hope it helps,

Luis
