(RADIATOR) AuthBy LDAP2: Hangs for 10 minutes when LDAP Server down

[r.helfenberger at comlight.ch]

Hello everybody
I found a timeout problem with Radiator when the LDAP server is down. The 
Radiator is completely blocked for about 13 minutes instead of the 
configured 10 seconds in the configuration file. This happens when one of 
the OpenLDAP serves is completely down (say LDAP_HOST1)

Configuration:
Radiator:   2.18.3 
Two OpenLDAP Servers.

Configuration file:

        <AuthBy LDAP2>
                NoDefault

                Host           LDAP_HOST1
                AuthDN     xxxx 
                AuthPassword  xxxx
                BaseDN         xxxx
                UsernameAttr   cn
                PasswordAttr   userPassword
                Timeout 10
                FailureBackoffTime 120
        </AuthBy>

        <AuthBy LDAP2>
                NoDefault

                Host           LDAP_HOST2
                AuthDN     xxxx 
                AuthPassword  xxxx
                BaseDN         xxxx
                UsernameAttr   cn
                PasswordAttr   userPassword
                Timeout 10
                FailureBackoffTime 120
        </AuthBy>

What I see in the logfile:
Fri Jun 28 15:06:18 2002: DEBUG: Handling with Radius::AuthLDAP2:
Fri Jun 28 15:06:18 2002: INFO: Connecting to 192.168.190.24, port 389
Fri Jun 28 15:19:27 2002: ERR: Could not open LDAP connection to 
192.168.190.24, port 389. Backing off for 120 seconds.

Fri Jun 28 15:19:27 2002: INFO: Attempting to bind with cn=radpay, 
ou=Users, ou=Administration, ou=Sunrise, o=Sunrise, c=ch, radpay (ser

The problem: between line 2 und 3 there is a gap of 13 minutes where the 
radiator was completely blocked. 

Did anybody else encounter such a problem? Is there a solution?

Thank you for your help

Best regards
