I submitted this first to the SASS repository and was redirected here. I reviewed the LESS files and the issue is the same there. While I reference specific lines in .scss files, from what I saw they are practically identical in their corresponding .less files.

My syntax will obviously be wrong when talking about LESS, but the suggestion is just to change the second instance of text to border, so I didn't convert my code. Then obviously this resolution will need ported to your SASS repository as well.

Thanks!

Original SASS issue:
twbs/bootstrap-sass#531

For the three has- classes (success, warning, error), the function call is currently using the -text color variable in the first two passes, but I believe the second should be the -border color variable. This would seem to be a correct fix based on the variable definitions in mixins.scss on line 857.

As it exists now (forms.scss line 272)

.has-success {
  @include form-control-validation($state-success-text, $state-success-text, $state-success-bg);
}
.has-warning {
  @include form-control-validation($state-warning-text, $state-warning-text, $state-warning-bg);
}
.has-error {
  @include form-control-validation($state-danger-text, $state-danger-text, $state-danger-bg);
}

Suggested change:

.has-success {
  @include form-control-validation($state-success-text, $state-success-border, $state-success-bg);
}
.has-warning {
  @include form-control-validation($state-warning-text, $state-warning-border, $state-warning-bg);
}
.has-error {
  @include form-control-validation($state-danger-text, $state-danger-border, $state-danger-bg);
}
