Kuv colleague tau ua haujlwm rau ib qho web nyob hauv ib lub chaw kawm FBA. Cov yam, cov Web site qhov cia li nkaum kiag tej cov ntaub ntawv los ntawm cov neeg rau zaub mov SQL. Lub hom phiaj grand During dictates tias ib cov DBA configures ntawv theem ruaj ntseg hauv SQL (as opposed to embedding ib tug neeg ID rau ib SQL cov lus nug los yog ib txhia lwm mus kom ze).

Qhov teeb meem yog tias SQL neeg rau zaub mov tsis paub dab tsi txog peb lub chaw FBA ces nws yuav tsis ntseeg peb. Solved tej teeb meem no yog peb, for lack of muaj ib lo lus zoo, manually impersonating tus neeg siv AD uas peb muaj txuas rau SQL xws tias SQL cov theem tej hauj lwm ruaj ntseg.

Txawm tias FBA yog ib qho kev feature ASP.NET, peb teb chaws SharePoint neeg tau qhia ntau yam tshawb engines uas yog koj nyob nraum querying FBA, koj yuav tsum txhais hais tias koj xav paub yuav ua li cas rau configure FBA nyob SharePoint. Kuv ua tsis tau tejyam rau nrhiav tej ntaub ntawv thiaj li yuav pab tau ib FBA oriented ASP.NET daim ntawv thov mus sib tham nrog SQL nyob rau hauv txoj kev uas peb yuav tsum tau xyuas.

Nyuam qhuav pib researching no, peb rov nyeem no Tshooj: ASP.NET Impersonation

Tshawb fawb coj peb mus no codproject Tshooj: http://www.codeproject.com/KB/cs/cpimpersonation1.aspx

Uas pab peb sau ntawv peb kev cai, uas kuv twb muaj nyob hauv qab. Nws yuav tsis tau cov khoom feem ntau elegant, tab sis nws ua haujlwm. Kuv vam tias koj pom tias nws yuav pab tau.

Ntawm no yog cov chaws uas ua haujlwm rau peb:
