I do not use MySQL a lot and I have never used Navicat before, but what I can see from the homepage, that this only is a GUI to administrate MySQL by wrapping SQL statements into a user-friendly interface.

Hence, I assume all what you essentially did is to perform a statement like:

UPDATE radcheck set attribute = 'Crypt-Password' WHERE attribute = 'Cleartext-Password'

Of course this does not change the value in the column 'value'. Why should it be otherwise? MySQL (and Navicat) does not know anything about FreeRadius. If you only update the column "attribute" nothing else will be modified. This is normal SQL behaviour. You are also responsible to modify the column "attribute" accordingly. This means you have to fill in the encrypted version of the password. No one else will do this for you.

As I said before you must use something like

UPDATE radcheck set attribute = 'Crypt-Password', value = SOME_FANCY_CONVERT_FUNCTION( value ) WHERE some_senseful_condition_here;

where SOME_FANCY_CONVERT_FUNCTION takes the cleartext and converts it into the encrypted version. I have never used FreeRadius with MySQL, so I cannot be more specific on SOME_FANCY_CONVERT_FUNCTION.

But I am astonished on some other fact. If you changed 'Cleartext-Password' to 'Crypt-Password' but did not change the value attribute, authentication must fail. Because FreeRadius now treats the value as the encrypted version which it is not. How can it be that you wrote nothing changed?

To be absolutely clear, the possible values for the 'attribute' column to specify a password are:

Cleartext-Password
Crypt-Password
MD5-Password
SMD5-Password
SHA-Password
SSHA-Password
NT-Password
LM-Password

The value of the 'value' column must be the correctly encrypted password with reference to what kind of password you use. That is what I meant by "change accordingly". And secondly everything must support the authentication protocol.
