I want to configure my Linux Servers (Most of them are Ubuntu servers) in such a way that an LDAP account is used to login into the servers in order to administer them. My objective is to achieve Single Sign On and centralization for user accounts.
I know that there are many Open Source LDAP solutions around there, but I would like to know how would you compare an Open Source LDAP solution vs Active Directory. What are the operative differences between an Open Source LDAP or just use Active Directory? So far I prefer to use Active Directory as far as I can integrate it with other Microsoft applications and I like it much more the way that it is administered and its way of replicating the AD database between servers. (Licenses required by AD are not an issue for me).
But... I have never made it, and I wonder if I can have any limitations using the LDAP offered by AD.
