Hello: ? Please inform me should I go for LDAP or stick with tdbsam. There are?forty computers here in my?institute?but we have more than 150 students here. It means there will be concurrent login of 40 users but need to create more than 150 roaming users which may gradually increase. Should I go for OpenLDAP. Is there any tool for autommated user creation of so many users. ? In anticipation of your reply ? Regards Rumman
