Need help configuring LDAP Bind

Getting the following error in the server.log from the ldap bind account when attempting logon in the web page:

12:43:03,476 WARNING [] (http-/ Internal authentication service exception: [LDAP: error code 49 - 80090308: LdapErr: DSID-0C09042F, comment: AcceptSecurityContext error, data 52e, v2580]; nested exception is javax.naming.AuthenticationException: [LDAP: error code 49 - 80090308: LdapErr: DSID-0C09042F, comment: AcceptSecurityContext error, data 52e, v2580]. Continuing authentication with some other provider.
12:43:03,585 DEBUG [] (http-/ User 'dataprep-tst' not found

I've confirmed the ldap.user string works with ldapsearch cli:

ldapsearch -H ldaps:// -x -w Password#1234 -D "CN=Fc-EO\, dataprep-tst,OU=Users,OU=CSV,DC=us,DC=lmco,DC=com" -b "DC=us,DC=lmco,DC=com" "(&(objectClass=person)(samAccountName=dataprep-tst))" cn sAMAccountName userPrincipalName

I've tried several variations for the ldap.user using the DN, CN and UPN, which all work with ldapsearch, but not with the rapid server.  I'm using TLS on all connections, but I've confirmed the CA certs and JKS are all good.

Appreciate any suggestions.
