LDIF Part
I usually get a task to review a LDIF file. I get a LDIF file and i have to "see" the data for whatever task I have to accomplish.
For example, I have to split a "sub tree" under a particular root suffix into a separate database for say replication reasons. I know that, I have to separate the entries of a branch, create a new database and import only those entries pertaining the branch.
Another example would be to just separate a particular branch for review purposes. Perhaps, I can run "ldapsearch" on the live server and obtain data. There are two issues that I usually come across, one is that I may not get access to the server in the first place, secondly, I may not get "all" the data. So, I generally request for a LDIF export of the root suffix so that I can work "offline" on the LDIF.
To address this most common challenge I wrote myself a tool called "ldifpart", written in perl. It would read the LDIF and provides with different levels in the hierarchy, then it can include/exclude to print only entries under a particular sub-tree. This will let me "split" the LDIF at any level of the tree.

$ ldifpart |
Let us look at an example. I wanted to just print the DNs of entries at different levels
|
$ ldifpart -d example_ldifpart.ldif |
Now, suppose i want to branch out "ou=Groups" container to another database then i would need a LDIF that contains only entries under "ou=Groups" including.
|
$ ldifpart -b "ou=groups,o=corp"
example_ldifpart.ldif |
Here is the script, and example LDIF.
Finally, the script normalizes the "DN" in the LDIF and unwraps the attributes that spawn across multiple lines. While this does not violate any LDIF standards some might perceive this as a "side effect". So, be warned. Enjoy.
