HI All,

Is there a way to do admin authentication for a normal user in dovecot IMAP ? I have a user using PAM to store password in /etc/shadow file. I need to authenticate the user in IMAP using that password. I tried using : -

I tried all combinations as below

[root@mail ~]# cat /etc/shadow| grep -i ajay ajay.lal:CM730q8foSA9A:13545:0:99999:7::: [root@mail ~]# telnet 0 143 Trying 0.0.0.0... Connected to 0 (0.0.0.0). Escape character is '^]'.

• OK dovecot ready. a1 login ajay.lal CM730q8foSA9A a1 NO Authentication failed. a1 login ajay.lal "{crypt}CM730q8foSA9A" a1 NO Authentication failed.

Also i tried [root@mail ~]# perl -MMIME::Base64 -e 'print encode_base64("\0ajay.lal\0{crypt}CM730q8foSA9A");' AGFqYXkubGFsAHtjcnlwdH1DTTczMHE4Zm9TQTlB

[root@mail ~]# telnet 0 143 Trying 0.0.0.0... Connected to 0 (0.0.0.0). Escape character is '^]'.

• OK dovecot ready. a1 AUTHENTICATE PLAIN

• AGFqYXkubGFsAHtjcnlwdH1DTTczMHE4Zm9TQTlB a1 NO Authentication failed.

My dovecot server does PLAIN authentication as can auth_mechanisms = plain

Is there a way to do PLAIN auth with crypt password or any means of doing admin authentication on behalf of normal user ?
