Hello: I''ve emailed this to the list before but I didn''t get an answer so I''m bringing this up again with a little bit more information. This problem seems to happen sporadically. I''m using Fedora DS 1.0.3 on the server. My client system in this case is a RHEL 3 WS box. When the user tries to login, the system will not accept his password. This doesn''t happen all the time though and I haven''t yet figured out how to "make" it happen. Here are the log messages on the client: Jun 20 17:12:57 low-tcw-104 sshd[14328]: pam_ldap: error trying to bind as user "uid=fallonma,ou=ISG,ou=Lowell,ou=People,dc=pii-dmz,dc=ext" (Constraint violation) I found some messages on the server side in the "errors" file that coincide with this user but the login attempt happens about 12 minutes after the error messages. The error messages on the server are: [20/Jun/2007:17:00:07 +0000] NSMMReplicationPlugin - agmt="cn=PII-DMZ TechOps" (low-mgt-100:389): windows_replay_update: failed to fetch local entry for modify operation dn="uid=fallonma,ou=isg,ou=lowell,ou=people,dc=pii-dmz,dc=ext" [20/Jun/2007:17:00:07 +0000] NSMMReplicationPlugin - agmt="cn=PII-DMZ IVRS" (low-mgt-100:389): windows_replay_update: failed to fetch local entry for modify operation dn="uid=fallonma,ou=isg,ou=lowell,ou=people,dc=pii-dmz,dc=ext" [20/Jun/2007:17:00:13 +0000] NSMMReplicationPlugin - agmt="cn=PII-DMZ IVRS" (low-mgt-100:389): windows_replay_update: failed to fetch local entry for modify operation dn="uid=fallonma,ou=isg,ou=lowell,ou=people,dc=pii-dmz,dc=ext" [20/Jun/2007:17:00:13 +0000] NSMMReplicationPlugin - agmt="cn=PII-DMZ TechOps" (low-mgt-100:389): windows_replay_update: failed to fetch local entry for modify operation dn="uid=fallonma,ou=isg,ou=lowell,ou=people,dc=pii-dmz,dc=ext" [20/Jun/2007:17:00:22 +0000] NSMMReplicationPlugin - agmt="cn=PII-DMZ IVRS" (low-mgt-100:389): windows_replay_update: failed to fetch local entry for modify operation dn="uid=fallonma,ou=isg,ou=lowell,ou=people,dc=pii-dmz,dc=ext" [20/Jun/2007:17:00:22 +0000] NSMMReplicationPlugin - agmt="cn=PII-DMZ TechOps" (low-mgt-100:389): windows_replay_update: failed to fetch local entry for modify operation dn="uid=fallonma,ou=isg,ou=lowell,ou=people,dc=pii-dmz,dc=ext" Is access to this user''s information somehow locked at this point? Is the replication doing something to the account? Thanks for any info. Aaron
