Dear Alan, Thank you for your prompt reply. As it is in the wiki: mysql> select * from radcheck; +----+----------------+--------------------+------------------+------+ | id | UserName | Attribute | Value | Op | +----+----------------+--------------------+------------------+------+ | 1 | fredf | Cleartext-Password | wilma | := | | 2 | barney | Cleartext-Password | betty | := | | 2 | dialrouter | Cleartext-Password | dialup | := | +----+----------------+--------------------+------------------+------+ 3 rows in set (0.01 sec) This is understood, but my attributes have to be validated with AND. For my understanding, I would need something like that: +----+----------------+--------------------+------------------+------+--------------------+------------------+------+ | id | UserName | Attribute1 | Value1 | Op1 | Attribute2 | Value2 | Op2 | +----+----------------+--------------------+------------------+------+--------------------+------------------+------+ | 1 | user | Cleartext-Password | password | := | 3GPP-IMSI | 262011234567 | == | Am I wrong?
