I am trying build new server Fedora 37 but when I trying to use PamMysql /because logins from postfix are stored in DB/ it is not working very strange is, that only one ask to saslauthd will stop and broke saslauthd I am using standard PamMysql and Saslauthd smtp.postfix in pam.d auth required pam_mysql.so user=postfix passwd=xxxx host=127.0.0.1 db=postfix table=mailbox usercolumn=username passwdcolumn=password crypt=1 account sufficient pam_mysql.so user=postfix passwd=xxxx host=127.0.0.1 db=postfix table=mailbox usercolumn=username passwdcolumn=password crypt=1 when I try only "testsaslauthd -u "yyy" -p "xxx" -s smtp" It fails, stops Saslauthd and write me "size read failed" Have anybody this error ?? on Fedora 37 ?? BTW: When I change SMTP.POSTFIX in PAM.D -> crypt=0 and write password to DB manually in cleartext - all works fine - but unusable, because of second one of mail - Dovecot is not able to authenticate cleartext passwords ;-) I think, that problem will be in crypting of SASLAUTHD...because in Dovecot same logins are not problem...and on my older server is not problem too BTW: I have built maybe 10 mailservers, same situation with no problems. but this is first on Fedora37
