Can I Use a Sequence Number in Netscape LDAP

[Adam Carroll]

I need to add some form of an object to my directory server that will act like a 
sequence number. Basically, every time a user is added, the number needs to get 
implemented by 1. So far, the best idea I've come up with 
is to have a plugin serve as a post-op plugin and handle the incrementing.

I was wondering if anybody else had ever had the need to do this and what solutions 
were used. Also, does Netscape have a native sequence data type?

Any help is appreciated -
