I hope this doesn't confuse you too much... First off... Your admin account will be dn="cn=admin,dc=oreillyauto,dc=com", if you are talking about the default admin account. You also want manage instead of write. I would also recommend securing your admin account with access lists, only allowing access from specific manager IP addresses. In order to restrict the cn=admin account as I do below, you have to set the userPassword attribute for the admin account, and blank the olcRootPW.
set admin password: dn: cn=admin,dc=bradley,dc=edu changeType: modify add: userPassword userPassword: {SSHA}<passwordhash>
blank old olcRootPW
dn: olcDatabase={1}hdb,cn=config changetype: modify delete: olcRootPW
This allows use of the normal authentication process and will look at your access lists. Otherwise, it will always bypass access lists and use the olcRootPW to authenticate.
Here's how I handle access restrictions, which I would suggest you evaluate. This is a positive security model as well (meaning the default action is deny), which I highly recommend (ie no one can access any field, unless it's specifically defined). The downside to the positive security model is that it's less flexible, you have to whitelist any new attributes you wish users to access, but it provides you with the best security. Another note in this, is that my user accounts are all shadowAccounts, and setting shadowInactive to 1 disables the account. (handled by the 3rd section with password fields).
Here is my access list in a template form:
dn: olcDatabase={1}hdb,cn=config changetype: modify replace: olcAccess # limit access to directory manager to local host only and specific manager ip's olcAccess: to dn.base="cn=admin,dc=,dc=" by peername.ip=127.0.0.1 auth by sockurl=ldapi:/// auth by peername.ip=<manager IP> auth by users none by anonymous none #Allow admin users full access to all attrs #Allow OpenLDAP2 Sync User read access to all #Everyone else, continue olcAccess: to * by peername.ip=172.16.0.0%255.255.0.0 dn="uid=adminuser,dc=,dc=" manage by peername.ip=<secondary ldap server ip> dn="uid=syncuser,ou=Service_Logins,dc=,dc=" read by peername.ip=<third ldap server ip> dn="uid=syncuser,ou=Service_Logins,dc=,dc=" read by * break #Handle password fields, for all possible entities.

I know this has to be super simple in what I am missing. My ldapadmin account cannot write to the database due to insufficient privileges.. This is the ACL part of the ldif file. Version 2.4.31 and this is from olcDatabase={1}hdb.ldif
olcAccess: {0}to attrs=userPassword by dn="uid=admin,dc=oreillyauto,dc=com" wr ite by anonymous auth by self write by * none olcAccess: {1}to dn.subtree="" by * read olcAccess: {2}to * by dn="uid=admin,dc=oreillyauto,dc=com" write by dn="uid=ld apadmin,ou=System,dc=oreillyauto,dc=com" write by * read
olcAccess: {2} for ldap admin actually be 'dn.base="uid=ldapadmin,ou-System, dc=<domain>,dc=com" write'?
