Hello,
We are getting this segmentation fault with freeradius v0.8.
We use ldap for authorisation, and kerberos for authentication, two Windows 2000 AD
servers (both for Ldap and kerberos).
The seg fault occurs while we restart any one of the servers, it use to work fine with
version v0.7.1.
Gdb output:
rlm_ldap: checking if remote access for chandra is allowed by radiusNPAllowDialin
rlm_ldap: looking for check items in directory...
rlm_ldap: Adding radiusNASPortType as NAS-Port-Type, value Async & op=21

I don't know how to use gdb very well.
