rlm_ldap not populating Stripped-User-Name

[Arnab Roy]

   Please ignore this resolved the issue. Somehow I had managed to move
   the call to suffix after the ldap call in the authorization section of
   the config. Arggh!! Apologies..

   Subject: rlm_ldap not populating Stripped-User-Name
   Hi ,
   Just wondering if one of you could help me with a strange issue that
   has suddenly appeared.
   Freeradius Version: 3.0.11
   It looks like rlm_ldap has suddenly stopped picking up the
   Stripped-User-Name value, my config looks like bellow
   user {
   filter =
   "(samAccountName=%{%{Stripped-User-Name}:-%{User-Name}})"
   scope = "sub"
   base_dn = "dc=domain,dc=com"
   access_positive = yes
   }
   All was working fine with this server for a while. The same filter is
   working fine in other modules like mschap and ntlm_auth. The exapnsion
   of the filter returns no value for the Stripped-User-Name parameter.
   Here is the grepd version of radiusd -X
   Any points where I could start looking would be much appreciated as to
   why it suddenly stopped.
