If you set up Adaptive Server master database replication in a warm standby environment, Sybase recommends setting longer password expiration intervals on the standby master database compared to the expiration intervals on the active master database. This allows the active master database to control any change of passwords and allows replication of password changes to proceed.
See Replication Server > Administration Guide Volume 2 > Manage Warm Standby Applications > Replication of the Master Database in a Warm Standby Environment for ASE.
