# To test this program, do the following
#Take a radius users' file, for example with:
#
#myuser Password = "apassword"
# User-Service = Framed-User,
# Framed-Protocol = PPP,
# Framed-Address = 255.255.255.255,
# Framed-Netmask = 255.255.255.255,
# Ascend-Metric = 2,
# Framed-Routing = None,
# Framed-Compression = 0,
# Ascend-Idle-Limit = 0,
# Ascend-Maximum-Time = 36000
#
#and do:
#
#cat users | ./radius2ldif
#
#Output is:
#dn: cn=myuser, ou=Hardware, ou=EDUCAMADRID, ou=People, o=icm.es
#objectclass: top
#objectclass: person
#objectclass: radiusprofile
#cn: myuser
#sn: myuser
#userpassword: apassword
#radiusServiceType: Framed-User
#radiusFramedProtocol: PPP
#radiusFramedIPAddress: 255.255.255.255
#radiusFramedIPNetmask: 255.255.255.255
#radiusFramedRouting: None
#radiusFramedCompression: 0
#
#dn: ou=RadiusUser, ou=Groups, o=icm.es
#description: RadiusUser
#objectclass: top
#objectclass: groupOfUniqueNames
#cn: RadiusUser
#uniquemember: dn: cn=myuser, ou=Hardware, ou=EDUCAMADRID, ou=People, o=icm.es
