RHEL 7.5 - Storing Automount Maps in LDAP not working

I followed the Red Hat document here:

(https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/storage_administration_guide/nfs-autofs#s2-nfs-config-autofs-LDAP)

But it does not work as stated. The above linked instructions state 3 tasks:

1. Verify BASE and URI are set correctly in /etc/openldap/ldap.conf:

TLS_CACERTDIR /etc/openldap/cacerts
SASL_NOCANON on
URI ldap://ldap02.testdomain.com/
BASE dc=testdomain,dc=com

2. edit /etc/autofs.conf to uncomment these lines:

map_object_class = automountMap
entry_object_class = automount
map_attribute = automountMapName
entry_attribute = automountKey
value_attribute= automountInformation

(By the way, the document seems in error stating /etc/sysconfig/autofs.
The location to uncomment is at /etc/autofs.conf. To be safe, I added these lines in both files.)

3. Create the autofs ldif and ingest it with ldapadd command:

dn: automountMapName=auto.master,dc=testdomain,dc=com
objectClass: top
objectClass: automountMap
automountMapName: auto.master

dn: automountMapName=auto.master,dc=testdomain,dc=com
objectClass: automount
cn: /home

automountKey: /home
automountInformation: auto.home

dn: automountMapName=auto.home,dc=testdomain,dc=com
objectClass: automountMap
automountMapName: auto.home

dn: automountKey=/home,automountMapName=auto.home,dc=testdomain,dc=com
objectClass: automount
automountKey: /home
automountInformation: ldap02.testdomain.com:/export/home/&

The above procedure as followed by Red Hat’s online documentation does not work.

When I try to ingest the autofs ldif I get this error:

ldapadd -x -D "cn=ldapadmin,dc=testdomain,dc=com" -f /etc/openldap/ldifs/autofs.ldif -W
Enter LDAP Password:
adding new entry "automountMapName=auto.master,dc=testdomain,dc=com"
ldap_add: Invalid DN syntax (34)
additional info: invalid DN

Has anyone been down this road and found out how to make this work ?

Background:
1. My test ldap server (ldap02.testdomain.com) works and I can login using ldap accounts.
2. I have autofs set up manually on one of my test clients to mount /home and that works outside of ldap.

Thanks for helping..
