I may not be an expert on the subject, but it seems to me that 99% of any LDAP server installation is used only to provide user authentication credentials and nothing more.
Given this restricted scope use, and being that exactly what I need, I would like to know if there are any simple SQL<->LDAP mapper implementing only posixAccount
objectclass, because it seems too cubersome to me to have another database to manage (like OpenLDAP) just for this, and I would like to use my already running PostgreSQL to provide the LDAP interface many software already supports.
