Inquiry Regarding Backslash Handling in Reply-Message

3 Sep 2025

      Hi!

We have encountered an issue in FreeRADIUS version 3.2.8 where the 
backslash (`\`) character in the `Reply-Message` configured for a user 
is not correctly reflected in the response.

---

**Configuration Details:**

In `mods-available/ldap2`, the following directive is set:

```
valuepair_attribute = "radiusAttribute"
```

The LDAP entry for `uid=user003` includes the following attributes:

```
radiusAttribute: Reply-Message += 'mess\age'
radiusAttribute: Reply-Message += 'mess\\age'
radiusAttribute: Reply-Message += 'mess\\\age'
radiusAttribute: Reply-Message += 'mess\\\\age'
```

---

**Observed Behavior:**

When PAP authentication is performed using this configuration, the 
response consistently contains only a single backslash, regardless of 
the number of backslashes defined in LDAP:

```
Reply-Message = "mess\age"
Reply-Message = "mess\age"
Reply-Message = "mess\age"
Reply-Message = "mess\age"
```

---

**Inquiry:**

If backslashes (`\`) within the LDAP database value are escaped as shown 
below:

```
radiusAttribute: Reply-Message += 'mess\\age'
radiusAttribute: Reply-Message += 'mess\\\\age'
```

Is it possible to modify the system so that the response reflects the 
intended number of backslashes, as follows?

```
Reply-Message = "mess\age"
Reply-Message = "mess\\age"
```

Any guidance or suggestions regarding this behavior would be greatly 
appreciated.

Best regards,
Satoshi Hirabayashi
