>Description:
At umich.edu, we have a convention of using timestamps in
logfile names. Currently, we have hard-coded logic
in kerberos to construct filenames of the form
<utility>.log.YYYYMMDD . This is obviously very site
specific, yet we'd rather not maintain site specific logic.
It would be nice if log file names could be expanded via strftime.
Show quoted text
>How-To-Repeat:
Run any kerberos daemon more than once. Watch it reuse
the same log file.

>Fix:
Compile-time fix, apply the patch in
/afs/umich.edu/group/itd/build/mdw/krb5.15x/patches/krb5-1.6.3-logts2.patch
configure with new --enable-logfile-by-date .
Change krb5.conf [logging] stanza, log file lines
to read like: FILE:/var/log/krb5kdc.log.%Y%m%d .
Restart daemons. Now see new style logfile names.
