PAM authentication failed on linux while installing MaxDB Database

Question

Seeing following errors in sapinst.log
INFO 2007-03-29 16:25:23
Account sqdln1 already exists.
ERROR 2007-03-29 16:25:25

And the XCMDOUT.LOG has following error:
ERR
-24875,ERR_NEEDADMI: The operating system user is not a member of the database administrators group
-24994,ERR_RTE: Runtime environment error
5,PAM authentication failed: Authentication failure
Here's the snippet from /etc/group
sapinst:x:500:root,ln1adm
sapsys:x:501:
sdba:*:502:sqdln1,root,sdb,ln1adm
Here's the relevant part from the /etc/passwd file:
ln1adm:x:500:501:SAP System Administrator:/home/ln1adm:/bin/csh
sdb:x:501:502:Database Software Owner:/home/sdb:/bin/csh
sqdln1:x:502:501:Owner of Database Instance LN1:/home/sqdln1:/bin/csh
Any idea why PAM is not authenticating the root user correctly? Even manually firing the dbmcli
gives the same error:
/sapdb/programs/bin/dbmcli  -n sapln1db -R /sapdb/LN1/db db_create LN1 CONTROL,vcs12345 sqdln1,vcs12345
ERR
-24875,ERR_NEEDADMI: The operating system user is not a member of the database administrators group
-24994,ERR_RTE: Runtime environment error
5,PAM authentication failed: Authentication failure
Please help.

The group and user entries are fine. I have modified the user and groups but still getting the same authentication error. I have disabled MD5 password authentication and now its just shadow. But still the problem persists.
Please help.
