pbrun is used to request that an application or command be run in a controlled account.

-u username sets the requesting user to be username.

In your case, the command dap is started for the user [username], it's not an option for pbrun.

Sorry @Rinzwind, OP asked:

Dap is a statistics and graphics program, that performs data management, analysis, and graphical visualization tasks which are commonly required in statistical consulting practice. Dap was written to be a free replacement for SAS, but users are assumed to have a basic familiarity with the C programming language in order to permit greater flexibility. Unlike R it has been designed to be used on large data sets.

You can download the application here. There are also deb files.

cd
wget
sudo dpkg -i dap_3.10-1_amd64.deb

The command in your question would display:

% pbrun -u guest dap

dap there is the command being run through PowerBroker. Full usage:

dap is not an option for pbrun. dap is the command that is to run under username through pbrun.

Dap is a small statistics and graphics package based on C. Version 3.0 and later of Dap can read SBS programs (based on the utterly famous, industry standard statistics system with similar initials - you know the one I mean)! The user wishing to perform basic statistical analyses is now freed from learning and using C syntax for straightforward tasks, while retaining access to the C-style graphics and statistics features provided by the original implementation. Dap provides core methods of data management, analysis, and graphics that are commonly used in statistical consulting practice (univariate statistics, correlations and regression, ANOVA, categorical data analysis, logistic regression, and nonparametric analyses).
