If Tableau Server is configured to use local authentication, the information you specify is used to create a new user in Tableau Server.
Note : After creating the user, you must set a full name, password, and email address for the user with the call to Update User. Even if it is not used by SAML, the user information must be present. If Tableau Server is configured to use Active Directory for authentication, the user you specify is imported from Active Directory into Tableau Server. When you add user to Tableau Online, the name of the user must be the email address that is used to sign in to Tableau Online.
After you add a user, Tableau Online sends the user an email invitation. The user can click the link in the invitation to sign in and update their full name and password. If you try to add a user using a specific site role but you have already reached the limit on the number of licenses for your users, the user is added as an unlicensed user. In that case, the response code is which indicates success , but the siteRole value in the response body is set to Unlicensed.
If the server uses local authentication, this can be any name. If you are using Active Directory authentication, or if you are using Tableau Online, there are specific requirements for the name. For most Active Directory users, these attributes are the same. By default, if you are adding a user from Active Directory, the name that you provide in the user-name is matched against the Active Directory sAMAccountName attribute, which becomes the name that the user signs in to Tableau Server with.
Two exceptions are when the name that you provide: is longer than 20 characters; and includes an character.

By contrast, he says, work refuting the efficacy of a compound to treat Chagas disease was quickly accepted 4. One-third of respondents said that their labs had taken concrete steps to improve reproducibility within the past five years. Free-text responses suggested that redoing the work or asking someone else within a lab to repeat the work is the most common practice. Also common are efforts to beef up the documentation and standardization of experimental methods.
Any of these can be a major undertaking. A biochemistry graduate student in the United Kingdom, who asked not to be named, says that efforts to reproduce work for her lab's projects doubles the time and materials used — in addition to the time taken to troubleshoot when some things invariably don't work. Although replication does boost confidence in results, she says, the costs mean that she performs checks only for innovative projects or unexpected results. Consolidating methods is a project unto itself, says Laura Shankman, a postdoc studying smooth muscle cells at the University of Virginia, Charlottesville.
After several postdocs and graduate students left her lab within a short time, remaining members had trouble getting consistent results in their experiments.
The lab decided to take some time off from new questions to repeat published work, and this revealed that lab protocols had gradually diverged. She thinks that the lab saved money overall by getting synchronized instead of troubleshooting failed experiments piecemeal, but that it was a long-term investment. He checks that all steps from raw data to the final figure can be retraced. But those tasks quickly become just part of the job. Once you learn it, it becomes a habit.
One of the best-publicized approaches to boosting reproducibility is pre-registration, where scientists submit hypotheses and plans for data analysis to a third party before performing experiments, to prevent cherry-picking statistically significant results later. Fewer than a dozen people mentioned this strategy. One who did was Hanne Watkins, a graduate student studying moral decision-making at the University of Melbourne in Australia.
Going back to her original questions after collecting data, she says, kept her from going down a rabbit hole. And the process, although time consuming, was no more arduous than getting ethical approval or formatting survey questions.
The survey asked scientists what led to problems in reproducibility. More than half pointed to insufficient replication in the lab, poor oversight or low statistical power. A smaller proportion pointed to obstacles such as variability in reagents or the use of specialized techniques that are difficult to repeat. But all these factors are exacerbated by common forces, says Judith Kimble, a developmental biologist at the University of Wisconsin—Madison: competition for grants and positions, and a growing burden of bureaucracy that takes away from time spent doing and designing research.
And the cost extends beyond any particular research project. If graduate students train in labs where senior members have little time for their juniors, they may go on to establish their own labs without having a model of how training and mentoring should work. Respondents were asked to rate 11 different approaches to improving reproducibility in science, and all got ringing endorsements.
Those ranked higher than the option of providing incentives such as funding or credit towards tenure for reproducibility-enhancing practices.
The survey — which was e-mailed to Nature readers and advertised on affiliated websites and social-media outlets as being 'about reproducibility' — probably selected for respondents who are more receptive to and aware of concerns about reproducibility.
Nevertheless, the results suggest that journals, funders and research institutions that advance policies to address the issue would probably find cooperation, says John Ioannidis, who studies scientific robustness at Stanford University in California. And given that these ideas are being widely discussed, even in mainstream media, tackling the initiative now may be crucial. Download the full questionnaire used in the survey and the raw data in a spreadsheet the data are also available as a tab-delimited file at Figshare.
The labels are now with the correct percentages. Begley, C. Nature , —
