unixODBC errors - undefined symbol:get_vtable

[Mohamed Imran (NBI)]

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.
