- Hi..
-
- The way passwords are stored on the sun under C2-security(or just
- running shadow passwords alone) are as follows:
-
- /etc/passwd
- root:##:0:1:Operator:/:/bin/csh ( Note ## replacing password field)
-
- /etc/security/passwd.adjunct - (note /etc/security is 700 )
- root:fdfdfsfsfd::::: ( Note the last 3-4 fields are for audit flags
- which if you are only running shadow password
- files(not full blown C2) you will not have any)
-
- The password.adjucnt file is usaully mode 600..
-
- "Basically" this is how all vendors shadow password files work..
-
- Note YP users!!! If you are running YP your passwd.adjucnt files will
- not be protected from causal users. Anyone can just
- "ypcat" the map.. This issue was discussed at length
- in alt.security(about 4 weeks ago).. Finally, all
- client machines will also have to be C2 converted..
