definition of tag= entries in logs

["Andrew Diederich" <diederic@boulder.net>]

I'm having problem some problems authenticating against openLDAP, and I  
think the answer may be in the openLDAP logfile, but I don't know how to  
read it right.  It looks like successful binds look like this:

Aug  9 08:36:17 servername slapd[16836]: conn=0 op=20 RESULT tag=97 err=0  
text=

and unsuccessful binds look like this:

Aug  9 08:35:03 servername slapd[11823]: conn=11771 op=108408 SEARCH  
RESULT tag=101 err=0 nentries=0 text=

The big difference as far as I can tell is the tag=101 vs the tag=97.   
I've gone through the code and the docs, but I can't figure out what the  
tag= means.  I think it uses some %lu variable from  
servers/slapd/result.c, but can't trace back to where the %lu comes from.

Does anyone have any ideas?  Thanks for the help.
