We want to install Single Sign on functionality for SAP, with BC-SNC, Kerberos 5 and Active
Directory, but when we configure SNC in SAP with kerberos we have a validation error as soon as
start SAP.
We have installed SAP over Linux which has Kerberos 5, the library that we are using is
The domain controllers of the AD are Windows 2003.

The configuration seems to be ok, we create the accounts in the AD (Linux server account
“hostname” and SAP Service account “SAPServiceXXX”), however when SAP starts we FIND the following

N  SncInit(): Initializing Secure Network Communication (SNC)
N        Intel x86 with Linux (st,ascii,SAP_UC/size_t/void* = 8/32/32)

N  <<- SncInit()==SNCERR_GSSAPI
N           sec_avail = "false"

I can’t find any information for the error code.
Could you please help me with this problem?

Thanks in advance!
