LDAP and RDBMS Integration

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Sun recently released a LDAP proxy server product which is advertised as 
a solution to this kind of problem.
The idea is it acts as a frontend LDAP server to multiple types of 
backend data sources.
Here's the man page to the commandline config program (dpconf), which 
will give you an idea of what it's supposed to be able to do:

I haven't used it personally, but looks like it might be of interest for 
you.
