I am attempting to setup a FreeRadius Server with an OTP (LinOTP) backend in Centos 7. My issue is loading a perl module needed to link FreeRADIUS to LinOTP. No matter what I try I just keep getting the error below when I try starting radiusd (with "/usr/sbin/radiusd -C -lstdout -xx"):
/etc/raddb/mods-config/files/authorize[46]: Parse error (check) for entry DEFAULT: Unknown or invalid value "perl" for attribute Auth-Type
Failed reading /etc/raddb/mods-config/files/authorize
/etc/raddb/mods-enabled/files[9]: Instantiation failed for module "files"
per documentation I have completed the following:
-added "DEFAULT Auth-type := perl" as the first and only uncommented line in /etc/raddb/users
-added the module location to /etc/raddb/mods-available/perl
-added the Auth-Type declarations in the site file (/etc/raddb/sites-available/linotp) see below.
-I have also tried copying the changes over to the default site but I get the same issue.
Here are the contents of the relevant files with comments removed (these things are 99% comments) /etc/raddb/users
DEFAULT Auth-type := perl
/etc/raddb/mods-available/perl
perl {
filename = /etc/raddb/mods-config/perl/radius_linotp.pm
}
/etc/raddb/sites-available/linotp

/etc/raddb/mods-config/files/authorize[46]: Parse error (check) for entry DEFAULT: Unknown or invalid value "perl" for attribute Auth-Type
Failed reading /etc/raddb/mods-config/files/authorize
/etc/raddb/mods-enabled/files[9]: Instantiation failed for module "files"
From this I can see the perl module being loaded but it seems something is not happy about the Auth-Type.
It may be an initialisation ordering issue. When you use attribute references like &Auth-Type in the policy language (within any of the virtual server sections like authorize { ... }, authenticate { ... } etc... There's a multi-pass resolution process that occurs. So even though the auth sections haven't been parsed at the point where you're setting values for Auth-Type is still works fine.
For the users file, which is an older legacy format from <= v2, there's no multi-pass processing. I can't remember in v3 without digging into the code which is initialised first, virtual servers or modules. But if it's modules, then your problem is almost certainly, that the attribute resolution in the files module is being done before the Auth-Type sections are being processed, and the complete set of Auth-Type values has been built.
The simple fix for this, is to manually provide an enumeration value for Auth-Type in the custom dictionary file.
Try adding the following to /etc/raddb/dictionary or /etc/freeradius/dictionary on Debian based systems.
That should allow the files module to get the correct enumeration value for Auth-Type before any of the virtual servers are parsed.
