You're right, [root@fsrv02 log.d]# ll /usr/lib64/sasl2/ total 0
:-( [root@fsrvpsg02 log.d]# rpm -qa | grep sasl2 lib64sasl2-2.1.23-1.1mdv2010.0 libsasl2-plug-plain-2.1.23-1.1mdv2010.0 libsasl2-plug-login-2.1.23-1.1mdv2010.0 libsasl2-2.1.23-1.1mdv2010.0 So I missed the point, I just installed the relevant lib64sasl2-plug, and it works. Thanks to all for your guidance, I think I was tired last night.
