I'm currently trying to get group based login working with little success
using pam_groupdn on CentOS. Currently, any existing LDAP user is allowed to login to the system, but it does throw the error: "You must be a member of cn=login,ou=Group,dc=mydomain,dc=com to login." I would like to deny logins for any ldap users unless they exist in the specified group (in this case, cn=login,ou=Group,dc=mydomain,dc=com). Can anyone tell me what I'm doing wrong or point me toward some documentation?
Your question has nothing to do with OpenLDAP and has everything to do with PAM. Read the docs for pam.conf.
