I just built a new proxy server and compiled the latest versions of squid and dansguardian. We use basic authentication to select what users are allowed outside of our network. It seems squid is working just fine and accepts my username and password and lets me out.

But if i connect to dans guardian, it prompts for username and password and then displays a message saying my username is not allowed to access the internet. Its pulling my username for the error message so i know it knows who i am. The part i get confused on is i thought that part was handled all by squid, and squid is working flawlessly.

Can someone please double check my config files and tell me if i'm missing something or there is some new option i must set to get this to work.

dansguardian.conf

# reportinglevel = 3

# Language dir where languages are stored for internationalisation.
# The HTML template within this dir is only used when reportinglevel
# is set to 3. When used, DansGuardian will display the HTML file instead of
# using the perl cgi script.  This option is faster, cleaner
# and easier to customise the access denied page.
# The language file is used no matter what setting however.
# languagedir = '/etc/dansguardian/languages'

# Non standard delimiter (only used with accessdeniedaddress)
# Default is enabled but to go back to the original standard mode dissable it. nonstandarddelimiter = on



# Banned image replacement
# Images that are banned due to domain/url/etc reasons including those
# in the adverts blacklists can be replaced by an image.  This will,
# for example, hide images from advert sites and remove broken image
# icons from banned domains.
# 0 = off
# 1 = on (default) usecustombannedimage = 1 custombannedimagefile = '/etc/dansguardian/transparent1x1.gif'



# Filter groups options
# filtergroups sets the number of filter groups. A filter group is a set of content
# filtering options you can apply to a group of users.  The value must be 1 or more.
# DansGuardian will automatically look for dansguardianfN.conf where N is the filter
# group.  To assign users to groups use the filtergroupslist option.  All users default
# to filter group 1.  You must have some sort of authentication to be able to map users
# to a group.  The more filter groups the more copies of the lists will be in RAM so
# use as few as possible. filtergroups = 1 filtergroupslist = '/etc/dansguardian/filtergroupslist'

# Raw is where the raw HTML including meta tags are phrase filtered
# CPU usage can be effectively halved by using setting 0 or 1
# 0 = raw only
# 1 = smart only
# 2 = both (default) phrasefiltermode = 2



# Lower casing options
# When a document is scanned the uppercase letters are converted to lower case
# in order to compare them with the phrases.  However this can break Big5 and
# other 16-bit texts.  If needed preserve the case.  As of version
2.7.0 accented
# characters are supported.
# 0 = force lower case (default)
# 1 = do not change case preservecase = 0



# Hex decoding options
# When a document is scanned it can optionally convert %XX to chars.
# If you find documents are getting past the phrase filtering due to encoding
# then enable.  However this can break Big5 and other 16-bit texts.
# 0 = disabled (default)
# 1 = enabled hexdecodecontent = 0



# Force Quick Search rather than DFA search algorithm
# The current DFA implementation is not totally 16-bit character compatible
# but is used by default as it handles large phrase lists much faster.
# If you wish to use a large number of 16-bit character phrases then
# enable this option.
# 0 = off (default)
# 1 = on (Big5 compatible) forcequicksearch = 0



# Reverse lookups for banned site and URLs.
# If set to on, DansGuardian will look up the forward DNS for an IP URL
# address and search for both in the banned site and URL lists.  This would
# prevent a user from simply entering the IP for a banned address.
# It will reduce searching speed somewhat so unless you have a local caching
# DNS server, leave it off and use the Blanket IP Block option in the
# bannedsitelist file instead. reverseaddresslookups = off



# Reverse lookups for banned and exception IP lists.
# If set to on, DansGuardian will look up the forward DNS for the IP
# of the connecting computer.  This means you can put in hostnames in
# the exceptioniplist and bannediplist.
# It will reduce searching speed somewhat so unless you have a local DNS server, 
# leave it off. reverseclientiplookups = off



# Build bannedsitelist and bannedurllist cache files.
# This will compare the date stamp of the list file with the date stamp of
# the cache file and will recreate as needed.
# If a bsl or bul .processed file exists, then that will be used instead.
# It will increase process start speed by 300%.  On slow computers this will
# be significant.  Fast computers do not need this option. on | off createlistcachefiles = on



# POST protection (web upload and forms)
# does not block forms without any file upload, i.e. this is just for
# blocking or limiting uploads
# measured in kibibytes after MIME encoding and header bumph
# use 0 for a complete block
# use higher (e.g. 512 = 512Kbytes) for limiting
# use -1 for no blocking
#maxuploadsize = 512
#maxuploadsize = 0 maxuploadsize = -1



# Max content filter page size
# Sometimes web servers label binary files as text which can be very
# large which causes a huge drain on memory and cpu resources.
# To counter this, you can limit the size of the document to be
# filtered and get it to just pass it straight through.
# This setting also applies to content regular expression modification.
# The size is in Kibibytes - eg 2048 = 2Mb
# use 0 for no limit maxcontentfiltersize = 



# Username identification methods (used in logging)
# You can have as many methods as you want and not just one.  The first one
# will be used then if no username is found, the next will be used.
# * proxyauth is for when basic proxy authentication is used (no good for
#   transparent proxying).
# * ntlm is for when the proxy supports the MS NTLM authentication
#   protocol.  (Only works with IE5.5 sp1 and later).  **NOT IMPLEMENTED**
# * ident is for when the others don't work.  It will contact the computer
#   that the connection came from and try to connect to an identd server
#   and query it for the user owner of the connection. usernameidmethodproxyauth = on usernameidmethodntlm = off # **NOT IMPLEMENTED** usernameidmethodident = off



# Preemptive banning - this means that if you have proxy auth enabled and a user accesses
# a site banned by URL for example they will be denied straight away without a request
# for their user and pass.  This has the effect of requiring the user to visit a clean
# site first before it knows who they are and thus maybe an admin user.
# This is how DansGuardian has always worked but in some situations it is less than
# ideal.  So you can optionally disable it.  Default is on.
# As a side effect disabling this makes AD image replacement work better as the mime
# type is know. preemptivebanning = on



# Misc settings

# if on it adds an X-Forwarded-For: <clientip> to the HTTP request
# header.  This may help solve some problem sites that need to know the
# source ip. on | off forwardedfor = on


# if on it uses the X-Forwarded-For: <clientip> to determine the client
# IP. This is for when you have squid between the clients and DansGuardian.
# Warning - headers are easily spoofed. on | off usexforwardedfor = off


# if on it logs some debug info regarding fork()ing and accept()ing which
# can usually be ignored.  These are logged by syslog.  It is safe to leave
# it on or off logconnectionhandlingerrors = on



# Fork pool options

# sets the maximum number of processes to sporn to handle the incomming
# connections.  Max value usually 250 depending on OS.
# On large sites you might want to try 180. maxchildren = 180


# sets the minimum number of processes to sporn to handle the incomming connections.
# On large sites you might want to try 32. minchildren = 32 


# sets the minimum number of processes to be kept ready to handle connections.
# On large sites you might want to try 8. minsparechildren = 8


# sets the minimum number of processes to sporn when it runs out
# On large sites you might want to try 10. preforkchildren = 10 


# sets the maximum number of processes to have doing nothing.
# When this many are spare it will cull some of them.
# On large sites you might want to try 64. maxsparechildren = 64 


# sets the maximum age of a child process before it croaks it.
# This is the number of connections they handle before exiting.
# On large sites you might want to try 10000. maxagechildren = 5000



# Process options
# (Change these only if you really know what you are doing).
# These options allow you to run multiple instances of DansGuardian on a single machine.
# Remember to edit the log file path above also if that is your intention.
