Kerberos credentials are defective

[Shu-ying.Yu@sybase.com]

Hi,

I have to use kerberos authentication to support authentication between 
sybase products.

An kerberos server has been setted up on the machine 
repsunsh.sybase.com(solaris platform)

I have a sybase ASE server on the machine :replinux4.sybase.com(linux 
platform) and user :shuyingy.

When i tried to login this ASE server by sybase client isql with kerberos 
authentication, i got such result:

ASE log error message:

00:00000:00016:2008/09/14 20:05:04.25 server  SCL error in function: 
sec_get_cred. Operation: sec_cred_acquire().
00:00000:00016:2008/09/14 20:05:04.25 server  SCL error in function: 
sec_setup. Operation: sec_get_cred().
00:00000:00016:2008/09/14 20:05:04.25 kernel  Connectivity Library 
(Security Control Layer) Error: Consistency checks performed on the 
credential failed (minor status 0).


but I have got credentials of the server and user.
klist:

Ticket cache: FILE:/remote/repeng1/ost/krb5/ost_replnx4_13
Default principal: shuyingy/replinux4.sybase.com at OST.SYBASE.COM

Valid starting     Expires            Service principal

ost_replnx4_13/OST.SYBASE.COM at OST.SYBASE.COM


Kerberos 4 ticket cache: /tmp/tkt10646
klist: You have no tickets cached

I think there was no error with my configure of kerberos since I have got 
the two credentials.

Could anyone help me about this problem?

Thank you very much.
