Hello, thanks for the report. I believe the session is terminating because of the symbol lookup error. The function pr_gid2str was not backported and the compiler was happy to accept that. I have changed the log message to not use this function. The message in general is correct though. Could you try the new package uploaded to https://people.debian.org/~apo/proftpd/ and report back, if it fixes your problem? Regards, Markus
