I patched one node of my cluster to SLES11 SP2 / OES11 SP1. After doing so I get the following error when trying to log in via ftp.

Sep 28 09:04:40 node2 pure-ftpd: (?@10.202.50.201) [4782] [INFO] New connection from 10.202.50.201

Sep 28 09:04:50 node2 pure-ftpd: (?@10.202.50.201) [4782] [ERROR] Login authentication failed

When the service is hosted by the node still running SLES11 SP1 / OES11 it logs in just fine. Does anyone else experience this issue?
