[Serusers] Bug report in pa module

Hi all, we're trying to connect Windows Messenger Clients to ser-0.10.99 We've configured ser with pa module. If I understand how it works : -U1 is connecting for the first time to ser. -U1 add his contacts, and each time he adds a contact, ser inserts the data in watcherinfo table. For exemple, he adds U2 inhis contacts. -U2 is connecting for the first time to ser. -presentity_contact table is updated and U1 can see that U2 is online. -U2 add his contacts, and each time he adds a contact, ser inserts the data in watcherinfo table. For exemple, he adds U1 inhis contacts. -Then presentity_contact table is updated and U2 can see that U1 is online. We've tested the two following configurations: -In one hand, if the Usernames of 2 clients are very differents, such as "Mohamed" and "Xavier", it works fine. -In the other hand, if the Usernames are something like "Xavier1" and "Xavier2" and each of them are in the contacts list of the other, then we found a problem while ser was trying to insert data in presentity_contact table. The s_id generated is the same for each user. Therefore, only the first user who was connected the first time will see the status of the other user. B.R. Xavier.
