Here is a solution the this problem that uses the metropolis algorithm to maximize the utilization of each group (ie get each group as close to the 1TB limit as possible).
All,
So, I have an ldif file that contains about 6500 users worth of data. Some users have a block of text I'd like to remove, while some don't.
Example (block of text in question is the block starting with "authAuthority: ;Kerberosv5"):
User with text block:

rand
rand(3UCB) SunOS/BSD Compatibility Library Functions rand(3UCB)NAME
rand, srand - simple random number generator
SYNOPSIS
/usr/ucb/cc[ flag ... ] file ...
int rand()
int srand( seed);
unsigned seed;
DESCRIPTION
rand() uses a multiplicative congruential random number generator with period 2**32 to return successive pseudo-random numbers in the range
from 0 to "2**31 -1."
srand() can be called at any time to reset the random-number generator to a random starting point. The generator is initially seeded with a
value of 1.
SEE ALSO drand48(3C), rand(3C), random(3C)NOTES
Use of these interfaces should be restricted to only applications written on BSD platforms. Use of these interfaces with any of the system
libraries or in multi-thread applications is unsupported.
The spectral properties of rand() leave a great deal to be desired. drand48(3C) and random(3C) provide much better, though more elaborate,
random-number generators.
The low bits of the numbers generated are not very random; use the middle bits. In particular the lowest bit alternates between 0 and 1.
