\fBIdent\fR (boolean)
If ngIRCd is compiled with IDENT support this can be used to disable IDENT
lookups at run time.
+Users identified using IDENT are registered without the "~" character
+prepended to their user name.
Default: yes.
.TP
\fBMorePrivacy\fR (boolean)
If ngIRCd is compiled with PAM support this can be used to disable all calls
to the PAM library at runtime; all users connecting without password are
allowed to connect, all passwords given will fail.
+Users identified using PAM are registered without the "~" character
+prepended to their user name.
Default: yes.
.TP
+\fBPAMIsOptional\fR (boolean)
+When PAM is enabled, all clients are required to be authenticated using PAM;
+connecting to the server without successful PAM authentication isn't possible.
+If this option is set, clients not sending a password are still allowed to
+connect: they won't become "identified" and keep the "~" character prepended
+to their supplied user name.
+Please note:
+To make some use of this behavior, it most probably isn't useful to enable
+"Ident", "PAM" and "PAMIsOptional" at the same time, because you wouldn't be
+able to distinguish between Ident'ified and PAM-authenticated users: both
+don't have a "~" character prepended to their respective user names!
+Default: no.
+.TP
\fBPredefChannelsOnly\fR (boolean)
If enabled, no new channels can be created. Useful if you do not want to have
other channels than those defined in [Channel] sections in the configuration
