           Summary: SASL Authentication fails if another client of sasl is
                    loaded
           Product: kio
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: imap
        AssignedTo: kmail-devel kde org
        ReportedBy: aroth arsoft-online com


Version:            (using KDE KDE 3.5.7)
Installed from:    Ubuntu Packages
OS:                Linux

This error occurs, if another module (kio slave) already loaded the libsasl library and initialized the library. 
 
In smtp.cc the function sasl_client_init is called with a set of callback functions. If another user of libsasl already called this function before and specified a different set of callbacks (or NULL), the second set of callbacks is ignored an the first set is used. 
In the kio_imap the callbacks must be specified to work with SASL mechanism which require callbacks to get username and password. But if the callbacks aren't installed because someone before has specified another set of callbacks all SASL mechanism which require callbacks aren't working (which left me with only three mechanisms Clear-Text, EXTERNAL and ANONYMOUS). 
As a result i can only retrieve my mail using the Clear-Text authentification. 
 
I think this issue also occurs on every other kioslave which uses the libsasl for authentication (see also https://bugs.kde.org/show_bug.cgi?id=146582)
