How to Build a Search Filter in LDAP Query

All, I would like to know how to build a search filter in ldap query in order to search for the users from a particular group for a given DN and OU. Please note that I am making use of LDAP Tools plugin.

Here's the information of the LDAP environment:

Full LDAP Server URL: ldap://myhostname:389
Service Manager Username: CN=Administrator
Service Manager Password: Welcome@123
Base DN: dc=appian
OU: hr (heirarchically falls under dc=appian)
scsExternalSystemKey: ldap.local

And here's how I have tried configuring the search filter in various ways, but I am unable to retrieve any results:

1. ldapsearch(
config:{
scsExternalSystemKey:"ldap.local",
usePerUserCredentials:false,
url:"ldap://myhostname:389",
baseDN: "dc=appian,ou=hr"
},
searchFilter:"(&(ObjectClass=inetOrgPerson)(uid=user.1)(memberof=CN=development,OU=hr,DC=appian))",
attributes:{},
pagingInfo:a!pagingInfo(
startIndex:1,
...
