I (my company) run a webservice that integrates pieces of few entreprisey-level software.
Most of them offer different type of authentication but all offers at least LDAP.
I was wondering if storing my application users directly in an LDAP directory would be a good idea. This way all the application I am using could rely on it for authentication purpose.
I am aware that LDAP is not a database per se, but it is a datastore. I am also aware that there is no kind of constraints thus deleting a user on the LDAP directory won't do anything on my actual data, but this case would be taken care of with an extra process.
My main question here is : is there any reason why I shouldn't use LDAP as my users database ?
