[RADIATOR] Issue with LDAP and SASL authentication

[Dubravko Penezic]

Hi,

few days ago we change from Debian 12 to Debian 13 , and working 
configuration of RADIATOR 4.30-1 stop working on part that connect to 
LDAP (OpenLDAP) service on same server.

Error is as following :

00b6e9f0 Tue Apr  7 15:38:58 2026 533634: DEBUG: Handling with 
Radius::AuthLDAP2:
00000000 Tue Apr  7 15:38:58 2026 533789: INFO: AuthLDAP2 Connecting to 
ldapi:/// port 389
00000000 Tue Apr  7 15:38:58 2026 534044: ERR: AuthLDAP2 Could not open 
LDAP connection to ldapi:/// port 389. Backing off for 60 seconds.

I did check slapd configuration end check ldapi:/// EXTERNAL 
authentication from command line, and impersonate like radiator user 
everything work correctly , "only" RADIATOR is not able to connect.

Any idea ? or debugging options ?
