See the config file section for more information. =item -e entry this is the entry to use in the config file. If it not specified, it will check the root. =item -T (0/1) 0 means it will be disallowed by default. 1 means will be allowed by default. If set to disallow it will disallow any attempts to log on to any towers that is not in the list. If set to allow it will do the oppasite. =item -t tower list This is a comma seperated list of towers that a account can log on to. =item -M (0/1) 0 means it will be disallowed by default. 1 means will be allowed by default. If set to disallow, any clients that try to log on with a MAC# not listed in the list will be disallowed. If set to allow, it will do the oppasite. =head1 CONFIG FILE The config file is a .ini file. The default config file is F<~/.mwcLDArc>. The entry over rides any thing found in the root for the .ini file. =item LDAPserver This is the IP# of the server that will be connected to. =item baseDN This is the DN that the users will be put into. =item LDAPuser This is the bind that will be made to the LDAP server. =item LDAPpassword This is the password that will be used for connecting to the LDAP server. This this is left out, it will prompt for a password. =item LDAPport This is the port that will be used for connecting =item ENVpassword If this is defined, it will check for the presence of a LDAPpassword enviromental variable. =item Example: LDAPserver=192.168.50.99 ;a freaking comment basedn=ou=users,ou=dhcp,ou=network,dc=fu,dc=bar [americanus] LDAPuser=cn=bufo americanus,ou=employees,dc=fu,dc=bar [alvarius] LDAPuser=cn=bufo alvarius,ou=employees,dc=fu,dc=bar LDAPpassword=somethingannoyinglyeasytofreakingremember =head1 LDAP notes See http://cpan.org/authors/id/M/MW/MWCZANECB/ for the required schema and more info on it. =head1 TODO =item Implement the static IP setting.
