If you use that way - and for some legitimate reasons I think is the way kolab webadmin is= acting - the hash can be or can't be supported. So probably you can upgrade ldap server or change the hash algorithm. Also you can try to change the password from console as in my example to validate my assumption.</p> <p>Mihai<span style=3D"font-family:monospace"><br> </span></p> <p><br> </p> <p><br> </p> <div class=3D"moz-cite-prefix">On 12/28/24 01:30, Valentin Laskov wrote:<br> </div> <blockquote type=3D"cite" cite=3D"mid:2697dd36-099a-47ee-bdf7-284093ee35= [email protected]">Hello, <br> <br> brute force method: <br> <br> 1.

But the new user can't login with roundcube ("Login failed" says roundcubemail). And the logs also say failed login. <br> <br> Old users can still login as usual with their password. <br> <br> After some investigation I found that "kolab user-info user@domain" shows a "userpassword:" with <br> <br> u'{SSHA512}................' <br> <br> and old users are encrypted like this: <br> u'{SSHA}................' <br> <br> I guess that with some system update something in the underlying system has changed and new passwords are beeing stored as SHA512 now, which makes roundcube or ldap fail to check the password. <br> <br> Has anyone help for me? Can I setup how roundcube webadmin will encode the password in LDAP? <br> Can I manually set the password in LDAP? <br> I'm not familiar with LDAP queries and need help with that. <br> <br> Have a nice Christmas :) <br> <br> Thomas <br> _______________________________________________ <br> users mailing list <br> <a class=3D"moz-txt-link-abbreviated" href=3D"mailto:[email protected]= ab.org">[email protected]</a> <br> <a class=3D"moz-txt-link-freetext" href=3D"https://lists.kolab.org/m= ailman/listinfo/users">https://lists.kolab.org/mailman/listinfo/users</a> <br> </blockquote> _______________________________________________ <br> users mailing list <br> <a class=3D"moz-txt-link-abbreviated" href=3D"mailto:[email protected]= .org">[email protected]</a> <br> <a class=3D"moz-txt-link-freetext" href=3D"https://lists.kolab.org/mai= lman/listinfo/users">https://lists.kolab.org/mailman/listinfo/users</a> <br> </blockquote> =20 <span>_______________________________________________</span><br><span>users m= ailing list</span><br><span>[email protected]</span><br><span>https://li= sts.kolab.org/mailman/listinfo/users</span><br></div></blockquote></body></h= tml>= --Apple-Mail-537B6FB6-6A46-437D-B68F-ACE15952CB94-- --===============1627753234910718310== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ users mailing list [email protected] https://lists.kolab.org/mailman/listinfo/users --===============1627753234910718310==--
