IBM Support

SSO connection is broken due to 25582 error

Troubleshooting


Problem

Informix SSO session issues may be experienced because of Kerberos GSS-API context expiration. Informix provides SSO support using Kerberos 5 and the Generic Security Services Application Programming Interface (GSS-API) open standards. Imformix Server support for SSO is provided as a separate communication support module called GSSCSM. Roughly speaking SSO GSSCSM module is an interface layer between Informix and system specific GSS-API library. Like Pluggable Authentication Modules (PAM) this authentication mechanism implies that Informix depends on OS specific implementation of MIT Kerberos GSS-API.

Symptom

When a client application establish a SSO session with Informix server the session may be finished with the error:

“25582: Network connection is broken”

when the Kerberos tickets expire.
