I need define a user /password for sasl but want that to do the verification automatically no -promting ( or even maybe avoid the verification) while using a tcp socket with some applications that need authentication (e.g libvirt) so I try : saslpasswd2 -c -p -a libvirt <user> and it hangs (if i now press Enter it says : "invalid parameter supplied") . if I avoid the -p flag the above commad works fine and prompts for password and later when using the tc p (virsh -c qemu+tcp:...) it prompts for the above defined user/password and autheticates ok . But I want without the prompting The man pages says -p Pipe mode - saslpasswd2 will neither prompt for the password nor verify that it was entered correctly. This is the default when standard input is not a terminal. In the past (before some upgrading of libvirt via rpm) the SASL authentication was done automatically no need for prompting Don't know how to restore it . Any help ? thanks Zvi Dubitzky Email:dubi@il.ibm.com
