Re: bash script for adding computers

[Jim C <jcllings@tsunamicomm.net>]

OK, I've gotten this far on the bash script I was writing to add a
machine.  It searches the base for uidNumbers, it sorts the numbers from
largest to smallest, takes the first one and adds one to it.  No sweat
right?

Here is the kicker,how do you get the data to ldapadd without creating
an ldif file?  I've tried an assortment of redirection techniques and 
I've also tried the bash "here" document.  In theory, this should be 
possible but I am having a really tough time figureing out the syntax.

#!/bin/bash

binddn="cn=root,dc=microverse,dc=net"
pw4binddn="passwordgoeshere"
ldaphost="ldap://localhost";
base="ou=Computers,dc=microverse,dc=net"
minimumUID=500
groupnum=421

store=`ldapsearch -LLL -D $binddn -H $ldaphost -b$base -x "(cn=*)"
uidNumber | \
                                                 grep uidNumber | \
                                                 sed -e 's/^uidNumber:
//' | sort -nr | head -n 1`

#It is best not to start at 0 or 1 as these could be privledged.

if [ "$store" = "" ]
         then
         store=$minimumUID
else
         store=`expr $store + 1`
fi
