# Synopsis
# applyQuotas.pl is a script solely for making the quota set within LDAP take
# affect by running the linuxquota tool edquota with the figures set in LDAP.
# This tool is capable of applying standard LDAP filters to the user-supplied
# base DN for applying multiple users' quotas at once. 

# Examples:
# Apply the quotas using the linuxquota tool edquota for user stefan
# ./applySystemQuotas.pl -b "uid=stefan,ou=People,dc=borgia,dc=com"
#
# Apply the quotas using the linuxquota tool edquota for all People with description of Student
# ./applySystemQuotas.pl -b "ou=People,dc=borgia,dc=com" -F "(description=Student)"
