title: Reasons to store users' data in LDAP instead of RDBMS
body: <p>It is often said that using LDAP is a good way to store data about users. That's beacause users' "directory" is hierarchical and it changes rarely. But in my opinion that doesn't exclude using RDBMS. What might be reasons to use LDAP? I guess that storing multi-valued fields or adding custom fields in LDAP might be easier but it can be done in database too (unless you have many records)</p>
