When the replay cache is set to "none" using the environment variable
KRB5RCACHETYPE=none
a memory leak occurs. This was detected when using OpenLDAP, Cyrus-
SASL, and GSSAPI authentication.
The following patch fixes the problem
diff -ur krb5-1.6.3/src/lib/krb5/krb/srv_rcache.c krb5-1.6.3um1/src/
lib/krb5/krb
/srv_rcache.c
