On Authentication Services systems running versions 126.96.36.199 and 188.8.131.5243, wildcard entries such as the following no longer work in user-override files:
The following message is seen in debug logs when the overrides are processed:
build_useroverride_db: Unable to find user/group from entry <*>, will re-process in 30 seconds
The following messages may also be seen when running a flush:
Processing user overrides... ERROR: Failed, returned or signalled 3
Processing group overrides... ERROR: Failed, returned or signalled 3
Product Defect 335285
The user-override processing was rewritten (327526) which introduced this new defect. Fixed in 184.108.40.206 and 220.127.116.1180, or later.
