I want to transfer many users for a uw-imap-server to a dovecot via imapsync. If I know the passwords all works fine. On the dovecot-side I create a "master-user" which allows access to all mailboxes. In uw-imap should it this feature too - but I can't find a FAQ to use this. Can someone help me?

In UW imapd, a user in group "mailadm" can do a SASL proxy authentication to any other user.

Hallo Mark,

thank you for your quickly answer.

I add the group mailadm, add a user uwmaster and give him a password and the primary group mailadm.
ssh-test with user/password ist OK.

By testing imapsync I got an error:

imapsync --host1 xx.xx.55.19 --user1 pro1 --authuser1 uwmaster --passfile1 sem1 --ssl1 --host2 xx.xx.55.22 --user2 pro1 --authuser2 dovemaster --passfile2 sem2 --ssl2

Error login : [xx.xx.55.19] with user [pro1] : 2 NO AUTHENTICATE PLAIN failed

In /var/log/messages I found:

Feb 23 12:36:01 r2 imapd[3473]: Failed uwmaster override of user=pro1 host=r22.j.de [xx.xx.55.22] Feb 23 12:36:01 r2 imapd[3473]: Login failed user=pro1 auth=uwmaster host=r22.j.de [xx.xx.55.22]

hint: uw-imap run on xx.xx.55.19, dovecot (and imapsync) on xx.xx.55.22
PLAIN-login enabled on both systems:
From capability : NAMESPACE MULTIAPPEND SASL-IR SCAN IDLE LOGIN-REFERRALS UNSELECT SORT BINARY THREAD=REFERENCES IMAP4REV1 MAILBOX-REFERRALS AUTH=PLAIN THR
EAD=ORDEREDSUBJECT AUTH=LOGIN LITERAL+
To capability : QUOTA NAMESPACE MULTIAPPEND SASL-IR AUTH=PLAIN IDLE AUTH=LOGIN LOGIN-REFERRALS UNSELECT LITERAL+ SORT CHILDREN IMAP4REV1 THREAD=REFERENCE

Any idea?


with regards
