Check your quotes-- you can't interpolate a variable within single quotes.
Personally, I went a bit more brute-force:
exec { '/usr/bin/sed -i -e s/uid=1000/uid=900/ *':
cwd => '/etc/pam.d',
subscribe => File['/etc/krb5.conf'],
refreshonly => true
}
But getting rid of minimum UID completely might have unexpected behavior--
do you really want to manage your root password via PAM_LDAP?
