Applies to: DirectControl for SAP running on IBM AIX 5.x, 6.1

Problem:

After restart of the SAP, SNC initialization failed and SAP Single Sign On failed to work. The following error is reported:

GSS-API(maj): Miscellaneous failure
GSS-API(min): Permission denied in replay cache code

Cause:

This error "Permission denied in replay cache code" is usually caused by a file permission (or file ownership) problem on the cache file.  On AIX systems, the cache file is located at /var/krb5/security/creds/krb5cc_xxx,  where the number xxx is the uid of the sap adm user.

Solution:

1. Check ownership and permission of /etc/krb5/krb5.keytab.  The sap adm account need access to the keytab file.
2. Check ownership and permission of /var/krb5/security/creds/krb5cc_###, where ### is the uid of the sap adm user.
3. If sap adm account have the permission to access both file, then try removing the cache file:
/var/krb5/security/creds/krb5cc_###
It will be created next time when the sap adm user login again.
