How do you square that with 1) two FBI agents "detailed to" the CIA's Bin Laden Issue station ("Alec Station"), 2) "CIA shared some details about al-Mihdhar with the FBI at that time"?
Compartmentalisation (i.e. an information "wall") does not equal a total ban on information sharing, as your comment might imply, it just mandates that there are filters and checks on information channels, rather than unfettered sharing, for obvious and sensible operational reasons.
Perhaps it's worth quoting at length from the source[1] for Wikipedia's statement that "CIA shared some details", which has a section on CIA / FBI information sharing:
> 4. Passing of intelligence information by the CIA to the FBI
> The CIA shares intelligence with the rest of the Intelligence Community through a communication known as a “TD” (“Telegraphic Dissemination”). TDs can be sent to other Intelligence Community agencies, including the FBI, and are available to the Intelligence Community through the Intelink system.
> Another type of intelligence report used by the CIA when conducting business with other agencies is a CIR, or “Central Intelligence Report.” CIRs are used for disseminating information to a specific agency or group of agencies. CIRs to the FBI normally concern something occurring in the United States, involving a U.S. person or an ongoing FBI investigation.
> In addition to formal methods of communicating by the CIA to the FBI, much information can be shared with the FBI informally. CIA and FBI employees who have similar positions and expertise develop relationships and communicate informally while working together on related matters, either by secure telephones or in person. In addition, meetings are sometimes held to discuss a matter or a piece of intelligence that is of value to both agencies. According to the CIA employees we interviewed, when the CIA passed intelligence information or other kinds of information verbally or by another informal mechanism to the FBI, the information exchange normally would be documented through a TD or a CIR. However, they said that not every telephone call or conversation was documented.
> C. FBI detailees to the CIA Counterterrorist Center
> In 1996, the FBI began detailing employees to work in the CIA’s CTC. During the time period relevant to this chapter of the report, five FBI employees were detailed to the CTC’s Usama Bin Laden Unit in four separate positions. Two of the positions were filled by personnel from the FBI’s Washington Field Office, and one position each was filled from the FBI’s New York Field Office and FBI Headquarters.
