Hints file can't match on prefix with back slash, forward slash works

Matt Cobb mattc at lockdownnetworks.com

In the hints file I want to look for one of two domains to pick which
ldap server to auth to.  Users are used to the DOMAIN\user syntax, so I
put in hint prefix checks for DOMAIN1\ and DOMAIN2\.  What I found was
that trying to match on the back slash doesn't work, despite trying
several checks with escaping.  A prefix check using a forward slash or a
postfix check using @ (user at realm) works fine.  Here is the
configuration of hints and users along with the output (1.0.2 radiusd
-X) of a login with TESTLAB\tester, which fails to set Auth-Type,
followed by a user TESTLAB/test which matches and sets the Auth-Type
successfully.

 

hints file...

 

DEFAULT         Prefix == "TESTLAB\", Strip-User-Name = Yes

            Hint = "LDAP2"

            

DEFAULT         Prefix == "TESTLAB\\", Strip-User-Name = Yes

            Hint = "LDAP2"

            

DEFAULT         Prefix == "TESTLAB\\\\", Strip-User-Name = Yes

            Hint = "LDAP2"

            

DEFAULT         Prefix == "TESTLAB/", Strip-User-Name = Yes

            Hint = "LDAP2"

            

DEFAULT Suffix == "@TESTLAB", Strip-User-Name = Yes

            Hint == "LDAP2"

            

DEFAULT         Prefix == "CORP\", Strip-User-Name = Yes

            Hint = "LDAP1"

            

DEFAULT         Prefix == "CORP\\", Strip-User-Name = Yes

            Hint = "LDAP1"
