Let openldap users change password with passwd in centos, i broke it

Tried to do the above with this tutorial:

https://www.unixguide.net/content/openldap-allow-users-change-their-password-unix-passwd-command

So I created this ldif:

dn: olcDatabase={2}hdb,cn=config
changetype: modify
add: olcAccess
olcAccess: to attrs=userPassword by self write by anonymous auth by dn.base="cn=ldapadm,dc=bbb,dc=local" write by * none

add: olcAccess
olcAccess: to * by self write by dn.base="cn=ldapadm,dc=bbb,dc=local" write by * read

Ran the ldapmodify, now no user can log into any client with their password when they could before I ran the above modify.

now attempting to login says permission denied after correct password is entered....what did I break ?? (totally new to openldap)

And as it might be relevant this is how I got my clients connected to my openldap server:

yum install -y openldap-clients nss-pam-ldapd
authconfig --enableldap --enableldapauth --ldapserver=192.168.1.10 --ldapbasedn="dc=bbb,dc=local" --enablemkhomedir --update

Out of the box, if I type passwd on an ldap user...the resulting happens:

[ldapuser@sdss5-db ~]$ passwd
Changing password for user ldapuser.
(current) LDAP Password: 
New password: 
Retype new password: 
password change failed: Insufficient access
passwd: Authentication token manipulation error

Though again that ldif file above with the olcAccess broke my ldap didn't make anything work (had to revert the VM back to before I ran that command..mostly because I am new to ldap and don't know how to remove items etc)

Here are all my cn=config files:

It seems it is not writing the second portion of:

add: olcAccess
olcAccess: to * by self write by dn.base="cn=ldapadm,dc=unixguide,dc=net" write by * read

To the olcDatabase={2}hdb.ldif , as going by the example it has olcAccess: {1}to * by self write by dn.base="cn=ldapadm,dc=unixguide,dc=net" write by * read

I am guessing this is what is not working and nuking the ability to login after I run the command. I am not sure why it is not showing up though as I get no errors when I run the modify command with my ldif posted above...

The result from the ldap modify is this:

[root@openldapserver ~]# ldapmodify -Y EXTERNAL  -H ldapi:/// -f passwordaccess.ldif
SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
