Unable to see LDAP references after adding them but still able to ldapsearch them - openldap

Question

I have set up two OpenLDAP servers on my network and am trying to enable authentication through LDAP. I am able to login to my servers if users are authenticated on the local LDAP server. However, after I add a reference object to the other server I can't see the object through phpldapadmin. Here's what I am adding with ldapadd.
dn: uid=server2,ou=People,dc=example,dc=com
objectClass: referral
objectClass: extensibleObject
cn: server2
ref: ldap://192.168.4.105/ou=People,dc=server2,dc=example,dc=com
It successfully adds but I am unable to see it through phpldapadmin. I can view it through ldapsearch this is what I get.
$ ldapsearch -h 192.168.4.106 -x -b "uid=server2,ou=People,dc=example,dc=com"
# extended LDIF
#
# LDAPv3
# base <uid=server2,ou=People,dc=example,dc=com> with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#
# search result
search: 2
result: 10 Referral
matchedDN: uid=server2,ou=People,dc=example,dc=com
ref: ldap://192.168.4.106/ou=People,dc=server2,dc=example,dc=com??sub
The fact that I can't see the objects and that they don't give me access to the other server is driving me nuts. I have nss_ldap and pam_ldap installed as well as the phpldapadmin module. I am running Ubuntu 13.04 on both servers. This is my slapd.conf for my client.

I would be really grateful if someone could point me in the direction of my problem. I'm not sure if this is related but I am unable to view my OpenLDAP server through Apache Directory Studio but I can see it through phpldapadmin.
