rlm_sql post-auth variable bug?

[Fernando Schapachnik]

Hi,
	In my AAA chain I have a module that *sometimes* adds a custom
attribute (defined in my dictionary as ipaddr) called Auth-NAS. This
module is called in the authorize section. Later on, in the post-auth
session I have a SQL-module that has:

postauth_query = "INSERT INTO ${postauth_table} (...)  \
		VALUES (.... \
                '%{check:Auth-NAS:-0.0.0.0}', ...)"

	When run, and Auth-NAS is not present, it outputs:

rlm_sql (sql-xxx) in sql_postauth: query is INSERT INTO table 
(...) ??VALUES (..., '=01', ...);


	Sometimes the '=01' is replaced by '255.255.255.255'.

	Is this a bug in some place or am I doing something wrong? Any 
ideas?

	Thanks in advance.


Fernando.
