How to find custom schema?

Question

Hello there,
I want to do a command line search to list all of my custom schema which we are using in the 99user.ldif file on Sun ONE 5.2Patch4.
I know how to add/mod/del using console, but i want to list all the extended objectclasses and attributes.
Can anyone tell me the search command? I appreciate it.
Thanks
SS

There is no easy way to do this. Even if you only look at attributes and objectClasses which have "USER DEFINED" ... you'll still get out of the box 5.2 Patch 4 Directory Server schema elements.
Here's what we did to work around the problem.
Dump the schema in LDIF format (using the -L flag with ldapsearch to get the entries in attribute: value format) and store to a file. Do this on your existing installation / deployment (the one with the custom attributes).
Dump the schema in LDIF format from a vanilla 5.2 Patch 4 install, with no modifications made at all to the schema, out to another file.
Join the lines in the two files (they're in LDIF format, so they wrap lines with a leading space) ... use the following command:
sed -e :a -e '$!N;s/\n //;ta' -e 'P;D' < myschema > $myschema.joined
sed -e :a -e '$!N;s/\n //;ta' -e 'P;D' < sunschema > $sunschema.joined
Sort each file.
sort myschema.joined > myschema.joined.sorted
sort sunschema.joined > sunschema.joined.sorted
Find the differences in the two files. These should be your custom attributes and objectClasses, with the server schema elements removed. All you have to do is cleanup the output (the diff utility will add some "<" and ">" characters to the beginnings of the lines).
diff myschema.joined.sorted sunschema.joined.sorted > myschema_extensions.txt
I really hope this helps. I don't think there is any easier way to do this, but I'll watch this thread hoping I get proved wrong! :-)
