Answer 1

"error code 49" indicates bad credentials (the credentials you are using to try to connect).

I assume that's this:

<Property name="ConnectionName">uid=wso2admin,ou=Users</Property>

According to the documentation , this property should be "the DN (Distinguish Name) of the admin user in LDAP". But your distinguished name is incorrect for two reasons:

1. You cannot use uid in a distinguished name (the example uses uid , but that doesn't work with Active Directory). It should start with CN= .
2. You're missing the domain part of the DN, like "dc=prc,dc=com" (I'm assuming that's what it is for your domain"

So it should look something more like this (but you will have to verify it is correct):

<Property name="ConnectionName">cn=wso2admin,ou=Users,dc=prc,dc=com</Property>
