Authenication problem

hangyu — Mon, 18 Sep 2006 20:21:51 GMT

I have two linux server and the openldap is running , I want to replicate all the user info. data between these two servers , so that if one of the server (eg. master server) is suddenly shutdown then another server (eg. slave server) may replace the user login function ( that mean user can automatically use slave server as user auth server while master server is shutdown ) , I try ldap replication but have problem so I am finding another method,
Another method I guess it may also ok , the step is copy the database ldbm in directory directive from master to slave then start it up , configure the /etc/openldap/ldap.conf to force the user find the password in master server first , if can't connect master server then automatically find it again in slave server , can advise is it possible ? please ignore the security issue.

I think you can setup in /etc/nsswitch.conf file

password files

or may be check in ldap config file.

You have to specify both local and remote server in /etc/openldap/ldap.conf:
HOST master.mydom.com localhost.localdomain
