In the example above, when _condition-1_ +evaluates to false, then _statements-1_ are skipped and _condition-2_ +is checked. When _condition-2_ evaluates true, then _statements-2_ +are executed. When _condition-2_ evaluates false, then +_statements-2_ are skipped and _statements-3_ are executed. + +As with xref:if.adoc[if], an `elsif` clause does not need to be followed by +an xref:else.adoc[else] statement. However, any xref:else.adoc[else] statement +must be the last statement in an `elsif` chain. An arbitrary number of +`elsif` statements can be chained together to create a series of +conditional checks and statements. + +.Example +[source,unlang] +---- +if (&User-Name == "bob") { + reject +} +elsif (&User-Name == "doug") { + ok +} +---- + +// Copyright (C) 2020 Network RADIUS SAS.
