No credentials cache found

[Barbat, Calin]

Hello,

I'm using MIT Kerberos V as an SNC provider to a SAP system running
under Linux. My current issue is a batch workprocess saying: GSS-API
(min): No credentials cache found
despite the fact that the /tmp directory is not full (55% free) and the
file /tmp/krb5cc_<UID> is in place and has permissions rw for the owner
<SID>adm user. Any idea why this situation occurs?

Thank you very much,
Calin Barbat
