Brian, 
 
Actually we have implemented a rudimentary relational database (non-sql) 
inside the server specifically to optimize for LDAP, however the engine core 
could be reused for an RDBMS.  Both and RDBMS and an LDAP server are databases 
really.   
 
Actually the combination of an RDBMS coupled with an LDAP server would be very 
powerful together.  If the data dictionary of an RDBMS is stored in LDAP the 
schema remains consistant across RDBMS instances and can be managed centrally 
and replicated easily.  Also works nicely for the storage of simple LUT based 
contraint tables.  You know the ones u use for an enumeration of options to 
constrain a column.  For example a LOAN table may have a TYPE column and there 
may be a LOAN_TYPES lookup table to constrain the column containing a single 
pk column of loan type varchars like so: 
 
Jumbo 
30 Year Fixed 
15 Year Fixed 
5 Year ARM 
 
etc ... 
 
LDAP would be great for storing LUT's where the reads are many and the writes 
are few.  It's not a core table for transactions like the LOAN table itself.  
This way several databases can leverage the same LUT data consistantly.  Also 
you can use delegation in LDAP to let the designated authority manage the 
additions to the LOAN_TYPES table. 
 
Another member on the LDAPd team named Robb which is CC'ed in this email has 
been discussing the potential for a common database library.  The library 
would have a storage managment layer, a index and a search engine with an 
optimizer for use in any database paradigm. 
 
Robb's an ex Oracle developer that helped design what is to be the system 
catalog for LDAPd.  He's valuable to us from a db engineering standpoint.  I'm 
sure he could play a pivitol role in working with the db folks.  But please 
don't take him from us just yet ;-). 
 
BU, 
Alex
