What does your /etc/ldap.conf look like?
Absolutely. pam_ldap/nss_ldap have undergone a series of changes "since then" and who's to say whether Rich has updated in sequence?
That's where Rich should look, and seek his solace on the pam_ldap and nss_ldap lists (www.padl.com).
Bottom line: Notwithstanding, RedHat 8's already a dead duck.
