Alfresco CIFS Server ERROR

Question

When I restart Alfresco, it starts... I got the page... But on the logs I got the error:

 2015-11-10 09:58:55,282  INFO  [management.subsystems.ChildApplicationContextFactory] [localhost-startStop-1] Starting 'imap' subsystem, ID: [imap, default]

2015-11-10 09:58:55,360  INFO  [management.subsystems.ChildApplicationContextFactory] [localhost-startStop-1] Startup of 'imap' subsystem, ID: [imap, default] complete

What is the error? How can I solve that?

Does the user running Alfresco have permissions to those ports? — Gagravarr
Depends on what operating system you're running. If you don't know how to check, ServerFault might be a better place for the question of how to do the check — Gagravarr
I already got the solution on the post of the ServerFault, but your answer was correct. So if you want to write in the answers. — PRVS

The key part of that error message is:

Error initializing TCP-IP SMB session handler, Permissão negada

That is telling you that when Alfresco tries to bind (via JLAN) to the port(s) needed to offer CIFS/SMB, it is getting permission denied

As you've found out over on your related question on ServerFault, on Linux by default a normal user can't bind to ports below 1024. CIFS/SMB make heavy use of ports down in the one hundred range, which regular users aren't allowed to listen on. Details of how to check that and how to fix it are a bit out of scope for StackOverflow, luckily they're covered in the answer on ServerFault :)

The other common error from that bit of code is "Address already in use", which you'll see if something else is already listening on the port(s) needed, eg another Alfresco server, or the machine's own CIFS/SMB stack.
