SNCERR_GSSAPI u2013 Logon error

35 Views

Good Morning,

I have implemented an SSO solution with Microsoft Active Directory 2003, SNC and kerberos5, with our SAP Systems (4.7 ext. set 2, Linux SLES 10 SP2).

It Works fine, but we have an error in some clients that I want to investigate.

Note that those clients never close the Windows session (reboot or shutdown of the PC) but they block-out their computers (CTRL-ALT-CANC).

Some days, when those users try to connect to SAP, they receive the following

error:

SNCERR_GSSAPI

An operation failed at the GSS-API level

Sec_avail=u201Dfalseu201D

Error in SNC

Detailed information states that it is in the SNC Component the return code was -4 and the counter 2. The method was SncInit in the sncxx.c.

The problem ends if the user close it windows session and start it again.

For technical reasons, a lot of my users can reboot the PC every day, so I have to figure out the reason of the problem and try to find a workaround.

Do you know this error?

Thanks in advance,

Federico Biavati
