.SH DESCRIPTION
Pass a char pointer as parameter to a string holding the \fIname\fP of the service
for DIGEST\-MD5, SPNEGO and Kerberos 5 authentication mechanisms. The default
service names are "ftp", "HTTP", "imap", "ldap", "pop" and "smtp". This option
allows you to change them.

option.

previous ones. Set it to NULL to disable its use again.
