Hi all, I've installed freeradius (built from source version: freeradius-server-3.0.9) on Centos 6.7 and am trying to get it to talk to our MS SQL servers (using unixODBC and FreeTDS driver) to lookup a mac address etc. as part of the post-auth process but not having much success. Running radius -X shows the following error: rlm_sql_unixodbc: 01000 [unixODBC][Driver Manager]Can't open lib '/usr/lib64/libtdsodbc.so' : ??vb??: undefined symbol: get_vtable rlm_sql_unixodbc: SQL down 08003 [unixODBC][Driver Manager]Connnection does not exist rlm_sql_unixodbc: Can't allocate the stmt rlm_sql_unixodbc: Socket destructor called, closing socket rlm_sql (sql): Opening connection failed (0) Has anyone else seen this issue? Any ideas on how this can be fixed? Also wondering if it's the version of unixODBC or FreeTDS im using is incompatible with this verison of freeradius. If so which version should I be using? Any help much appreciated. ================================ Environment details: ================================ OS: Centos 6.7 Freeradius: freeradius-server-3.0.9 [built from source as the repo version 3.0.3 kept throwing segmentation fault error] unixODBC: (from centos repo) Arch : x86_64 Version : 2.2.14 Release : 14.el6 FreeTDS: (from centos repo) Arch : x86_64 Version : 0.91 Release : 2.el6 ==================================== Regards, Mohamed Connect with us on: <https://twitter.com/NBIPComputing> The NBI Partnership Ltd provides non-scientific services to the <http://www.jic.ac.uk/> John Innes Centre, the <http://www.ifr.ac.uk/> Institute of Food Research, <http://www.tgac.ac.uk/> The Genome Analysis Centre and <http://www.tsl.ac.uk/> The Sainsbury Laboratory Disclaimer: This e-mail message may contain confidential information and is intended only for the use of the intended recipient(s).
