groupSearchFilter is not checking if the user is part of the group

[xanpri]

I'm using the MeshCentral application and trying to configure ldap to use groups. But group authentication is not working.
I use Open LDAP to authenticate Linux systems and workstations.

Here's the configuration I'm using:

"ldapOptions": {
    "url": "URL",
    "bindDN": "USERBIND",
    "bindCredentials": "SUPERPASS",
    "searchBase": "ou=test,dc=DC,dc=DC,dc=br",
    "searchFilter": "(&(objectClass=posixAccount)(uid={{username}}))",
    "groupSearchBase": "ou=test,dc=DC,dc=DC,dc=br",
    "groupSearchFilter": "(&(objectClass=posixAccount)(cn=group1)(memberUid={{username}}))",
    "tlsOptions": { "rejectUnauthorized": false }
	},

Group1 data for groupSearchFilter search:

dn: cn=group1,ou=test,dc=DC,dc=DC,dc=br
cn: group1
gidNumber: 11111
objectClass: top
objectClass: posixGroup
memberUid: user1
memberUid: user2
memberUid: user3

What could I be doing wrong in the group consultation?
