We are expecting that the LDAP connection closes after the authentication search but it is not happening.

This is what we would want to see in the logs:-

```auto
    [logs]$grep conn=1138167 access

    CONNECT conn=1138167 from=XXXXXXXXX to=XXXXXXXXX:XXXX protocol=LDAPS
    BIND REQ conn=1138167 op=0 msgID=1 type=SIMPLE dn="cn=XXXXXX,ou=users,o=XXXXXXXXX" version=3
    BIND RES conn=1138167 op=0 msgID=1 result=0 authDN="cn=XXXXXX,ou=users,o=XXXXXXXX" etime=1
    **DISCONNECT conn=1138167 reason="** Client Disconnect **"**

```

This is the config that we are using for LDAP connectivity -

```auto
    xpack:
      security:
        authc:
          realms:
            ldap:
              ldap1:
                bind_dn: cn=XXXXXXX,ou=XXX,ou=apps,o=XXXXXXXXXXXXXXX
                group_search:
                  base_dn: ou=XXX,ou=apps,o=XXXXXXXXXXXXXXX
                  filter: uniqueMember={0}
                order: 0
                ssl:
                  certificate_authorities:
                  - /etc/elasticsearcarch/ELK-LDAP.pem
                unmapped_groups_as_roles: false
                url: ldaps://XXXXXXXXXXXXXXXXXXX
                user_search:
                  base_dn: ou=users,o=XXXXXXXXXXXXXXX
                  filter: (&(objectclass=scbperson)(|((ismemberof=cn=XXXXXXXX,ou=XXX,ou=apps,o=XXXXXXXXXXXXXXX))(cn={0}))
            native:
              realm1:
                order: 1 

```
