libgssapi_krb5.a Kerberos SAP AIX

Hi ! 
We are trying to configure SNC in 
heterogeneous environment: SAP 
application server (AIX 4.3.3) and 
frontends on Windows 2000 & XP 
platforms in order to use only the 
SSO functionalities. we have decided 
to implement the SAP GSS-API 
supported solution : Kerberso. So we 
have installed a Kerberos client on 
our application server and a 
Kerberos domain controller on 
Windows 2000 server. The Kerberos 
client 
works fine, but we get a problem 
with the gss-api libgssapi_krb5.a. 
When we put the libgssapi_krb5.ain 
the kernel directory ( .../exe/run) 
and activating the SNC parameters in 
the instance profile, the sap 
systems starts but it does not allow 
any connection to the system. We 
have noticed that the work processes 
at the operating level are not 
started. 

Notice: 
- The library has all the necessary 
authorisations. 

- When we tried with an AIX 5.2 
platform we got the message : 

B db_con_shm_ini: WP_ID =12, WP_CNT

Hi Arezki,

I think you can't use the static library. Try the shared one.
