Greetings !!
Greetings,
Before going for Fedora Directory Server, I thought of going through the
feature list to see what all additional features
are supported when compared to OpenLDAP.
The list is long :-)
Though the feature list and FAQ says about many features
supported by Fedora Directory Server (like multi-master replication,
nested roles, cascading using hubs etc), they
don't provide information about some common features that
are supported by OpenLDAP. Some of such features include,
support for SNMP,
Supported.
password hashing,
Supported hashes are Crypt, SHA, and Salted SHA.
support of LDAP search
filters such as presence, equality, inequality, sub-string, approximate
and boolean operators,
This is part of the LDAPv3 standard.
support for consumer-
initiated replication,
Fedora DS does not support SyncRepl, if that's what you are asking.
support for supplier-initiated
replication,
Supported in single-master and multi-master replication models.
support for Digital certificates,
Supported for 8 years already.
support for
XMLDAP gateway and whether the Directory server support
XML for integration with external applications. XML and
XMLDAP are not supported by OpenLDAP too, I believe.
DSML is the standardized markup language for LDAP, and this is supported
in Fedora DS via the included DSML gateway process (java process).
Fedora DS is a direct and immediate descendant of the Netscape DS, which
was the first commercial LDAPv2 implementation in the world. Now it's at
LDAPv3. Netscape invented most of these features, and OpenLDAP project
started in 1999 to basically try to implement the core server and some
of these Netscape features.
If you ask me, the only real benefit to using OpenLDAP today is the
abundance of strange backends, e.g. if you want to make a really special
purpose LDAP server. You can make a directory out of just about any
arbitrary data source, etc. Writing backends for Fedora DS is also
possible, but there aren't too many available at the moment.
