rlm_ldap: default_profile not expanded

[Giovanni Lovato]

Is the default_profile setting in modules/ldap supposed to expand 
runtime variables?

I tried to set:

default_profile = "cn=default,ou=%{Realm},ou=profiles,dc=mc,dc=com"

but on the logs I see:

rlm_ldap: performing search in 
cn=default,ou=%{Realm},ou=profiles,dc=mc,dc=com
rlm_ldap: object not found

If I set:

default_profile = "cn=default,ou=company,ou=profiles,dc=mc,dc=com"

it works.
