The same problem with mkdir as was reportedly just fixed in wu-ftp exists with the Kerberos versions of FTPD as shipped in krb5-workstation-1.1.1-16
Did krb5-workstation-1.1.1-21 not fix this?
Yes, krb5-workstation-1.1.1-21 did fix it. It embarassing but also disapointing, that up2date had crapped out several times in succession so we didn't realise that we were missing updates even though we'd run it. 1.1.1-21 was applied by hand and all is well. Thanks
